Correlations to Success (draft)#
Abstract#
Students (n=210) in the Computer Science pre-major course at UW Bothell, Introduction to Programming II (CSS 143), responded to a multiple-choice survey four weeks into a ten week quarter. Fewer than 5 students did not respond the survey. The resulting data were analyzed by examining each question for correlations with a higher grade in the class. Two populationsâleft and rightâwere created by comparing opposite ends of participant answers and conducting a Student-t tests to determine whether there were significantly different mean grade values. Fourteen questions produced responses that formed populations with differing performance levels. Those that performed better are considered to be in the right group and to possess an âAdvantaged Featureâ. Students with a higher count of advantaged features (nine or more out of fourteen) showed a strong correlation with academic success. This report explores the data and explains the processes used, but it does not attempt to explain the underlying reasons or suggest actions.
Introduction#
This study sought to identify correlations to success in University of Washington Bothellâs Introduction to Computer Programming II (CSS 143) by examining student grades to demographics and answers to survey questions. A survey was administered in week 4 of a 10-week quarter for five different sections during the 2024-25 school year. All the sections were taught by the same instructor, Mr. Stride. There were 210 total respondants with fewer than 5 students not responding. Each participantâs grade in 143 was recorded.
All questions were multiple choice. There were several types of questions: Yes/No, Radio Options (4 or 5), Range of 1-5, Checkboxes (check all that apply). Many of the columns were mapped to values 1-5, and others were 1-hot encoded so that the most answers could be numerical. Specifics are explained in the Data Description section below. The data were explored by dividing the answers into two groups, a left and right group. For example, for a Yes/No question (mapped to 1/0), we examined to see if the grades of the students who answered Yes
vary significantly from those who answered No
. When the values had a range, the grouping depended on the quantity of the selections and where differences were revealed. For example, grit1
split the answers so that the left side comprised [1, 3]
and the right side was [5]
. The specifics on how each grouping was done is provided below.
The data were inspected for correlations primarly by: Cohenâs d value, Pearsonâs Coefficient, and Student-t p-value. Here is a brief explanation of Table #1.
Descriptions for what each

Table #1 |
Letâs briefly examine the top feature, 142grade
, to illustrate what the tableâs values mean. We can see that those in the ârightâ group (students with a higher 142grade
) had an average grade increase in the CSS143 course of 1.34 ± 0.399 (95% confidence) over those in the âleftâ. The Null Hypothesis that the left and right groups have the same mean value is strongly rejected because the p-value = 5.740e-10.
Areas of Interest
We will explore some areas of interest:
CodeTime
: For those students who ranked themselves in the middle ofdifficulty
andgrit1
, there was a correlation to time spent coding each week. There was no correlation for those on either end.Gender
: Males & females performed virtually identically.selfeval_
: Students who performed well ( >= 3.6) credited their prior course work and the instructor for their performance more than the poor performing students (<= 2.0). Regarding the remaining performance explaination options, poor-performing vs well-performing students did not explain their performance significantly differently.adv_count
: The count of Advantaged Features correlates strongly to how well a student does in the course. Once a student gets to 9 (of 14) advantages, there is a very strong chance the student will perform well.race
: Black students performed worse than other races. Black students had very few Advantage Features.1stgen
: A first generation student was more likely to have fewer advantages and to perform poorly. A first generation student at a specific Advantage Feature count was likely to perform as good as other students at the same advantage count.142x
: The number of times a student took CSS 142 does not correlate to performance in CSS 143.143x
: The number of times a student previously took CSS 143 does not correlate to better performance, and those students tended toward a negative correlation (although not significant enough; p-value = 0.076). A student who took the course before is not more likely to perform better.
Advantage Feature Count
If a student falls in the ârightâ data set, we consider this to be an advantage. In an effort to identify a 3rd Cause for 1stgen
and race
, we will at times excluded these two immutable features and call the remaining 12 âAdvantaged Features Mutable.â We counted how many advantages each student had and named this adv_count
and adv_count_mut
. Similar to the features themselves, we bisected the students into two groups: left = those who had 4/3 or fewer; right = those with 8/7 or more. These two groups had the following statistical values:

Here we see how the 36 students with a high advantage count performed significantly better than the other students. The curve shows the probability distribution while the table uses actual percentages from the data. Only 14% of students with 5 or fewer advantages achieved a 3.5 or better in the course, while 86% of students with 9 did.
Data Description#
Data from 5 sections over 3 quarters in 143 class taught by Mr. Stride. Data was collected in the 4th week of the course and so some students may have already withdrawn from the course. All data is self-reported except for the grade in 143. This is important because some answers may be accidentally wrong (e.g. overall gpa), and other answers will reflect intentions and not necessarily reality (e.g. grit, attendance). Two questions were give to only 2 sections (Attendance, Recency of 142). Show the questions, how they are mapped to shortened column names.
The data went through several stages:
Partial Raw Data: Three different files representing the studentsâ answers. This data is not anonymized.
Full Raw Data: The three different quarters were concatenated together. Any corrected typos and added questions were manually corrected
Grade & Anonymous Data: The studentsâ grades were joined with student names, and then the names and section information were removed.
Final Data: Answers were mapped to values. Multi-checkbox answers were broken out into a 1-Hot encoding. Each student Advantage Count was calculated and added.
All in all, there were 55 Features extracted from the survey questions, and then two were derived from the top 14 (adv_count
, adv_count_mut
).
Top 14 Feature Descriptions#
Recall that the student, on week 4 of the 10 week course, self-reported all data except for their 143 grade. Except where noted, a value of 5 indicates the better score.

Demographis: Age, Gender, Race, Retakes#
Here are a few pie charts exploring the demographics of the participants.

Gender#
There were no statistical differences between male and female students. The chart estimates the continuous probability density function (a KDE plot) of Male vs Female. It clearly shows virtually identical distribution. Note that the distribution is intentionally cut off at zero and 4.0. The legend provides the count of male & female students (151, 56 respectively).
In the charts below youâll see bar charts showing the distribution of grades across genders. We leave out Gender X and âPrefer not to sayâ because there are so few.

Shows the percentage of male and female students achieving a grade. Having the the y-axis be a percentage helps the reader compare the two groups. |
Grit, CodeTime & Credit#
There were two questions related to grit that are mapped to grit1
and grit2
. There were no correlations found for grit2
. Below is how the grit1
question was presented and mapped to values. This is what we will use for âgrit.â
The count of students at each grit value were: 3, 46, 107, 54. This means that only 3 students said that they tend to give up quickly. Over half of the students claimed that they âpersevere and suffer through itâ. The students were not given the mapping, and nowhere in the question was the word âgritâ referenced.
Complete this sentence in the way that is most like you:
When I get stuck...
grit1_map = { 'I tend to give up pretty quickly.': 1,
'I give up after a good amount of effort.': 3,
'I persevere and suffer through it.': 4,
"I enjoy the challenge; I just can't let it go.": 5 }
No one claimed to spend less than an hour per week on coding.
On Grit/Difficulty vs CodeTime#
The above chart examines six groups that were created by filtering down to students whose grit1
or difficulty
are a certain value. We group the students by how much they code per week (codetime
), and see if time spent coding has an impact on their mean 143 grade. The columns Left
and Right
indicate which subgroups were compared against each other when calculating the p-value using the Student-t Test.
The p-values only reach a level of significance for those student who are in the middle of difficulty and grit. We see that student who rate themselves in the most common difficulty category (4), that students who do 1-2 hours of coding per week perform significantly worse than students who do 3+ hours.
For students who rate themselves in the most common grit category (4), that students who do 1-2 hours of coding per week perform significantly worse than students who do 3-6 hours per week. Furthermore, students who code for 3-6 hours per week actually perform better than those who do 7+ hours. Perhaps this is due to diminishing returns for students who really struggle.
This data, and other charts, illustrate that for those with high grit, time spent coding does not correlate to a better grade.
We can summarize this way:
There are some students who are bound to do well or poorly (given their Difficulty and Grit level) for whom spending more time coding wonât make a difference. For the majority of students who are in the middle, coding 3-6 hours per week improves their grade over doing less. Coding for 7+ hours per week may indicate an insurmountable skills gap.
Credit-Blame#
Below youâll see how students give credit/blame for their performance. The p-value was derived using a 2-Proportion Z-Test. We see that Good Performers are more likely to credit the instructor for their good performance than Poor Performers are to blame the instructor for their poor performance (p-value = 0.008). Similarly, Good Performers are more likely to credit their prior course work for their performance (p-value = 0.024). While it appears that Poor Performers are more likely to blame their Test Taking ability, it is not statistically significant (p-value = 0.122).
Pearson Correlation#
All the Features were graphed and statistically analyzed against the 143 Grade. This investigation was used to derive the Advantage Features. While, statistically, it is possible to get a false positive here, we limited the p-value to be less than 0.02 to reduce the chances of a coincidental correlation. In the abstract, youâll find the table that shows the top 14 Features with their statistics. Below youâll see a graph that illustrates their Pearson Correlation (absolute value) to the 143 Grade. This Pearson Correlation uses the Featureâs value and does not consider left vs right groups.

Whisker Plots (Top 14 Features)#
These whisker plots show the spread of the CSS 143 grade for every value for the top 14 Features.
Whisker Plots (Other Features)#
These whisker plots show the spread of the CSS 143 grade for many of the remaining features.
1st Generation & Race#
First generation and Black students performed worse than their counterparts. There were only 14 Black students which is too few data points to find much significance, statistically. Below you can see how many Advantaged Features that Black and 1st Generation students had. It is apparent that Black students did not have as many Advantaged Features. This makes it difficult to know if being Black correlates to features that cause bad grades, or if being Black is, in and of itself, a feature that causes bad grades.
First Generation students did have plenty of Advantaged Features. While it mayt appear that First Generation students with advantages performed a bit worse than other students with the same count of advantages, the statistics do not bear this out. This could be due to our sample size being too small.
First Generation students had fewer advantages overall (p-value = 0.004). The distribution of Advantage Count (Mutable) is skewed to the left.
We examined students at each Advantage Count (Mutable) to see if their mean 143 Grade was significantly different. The table below shows the p-value derived from a Student-t test at each advantage count. None of the p-values were below 0.05.

Below we see a scatter plot of student grades by Advantage Count (Mutable). The plot shows 4 subcategories of students. Non-Black, Non-1stgen students had a higher advantage count. Even at lower advantage counts, the line of best fit indicates that these students would perform better than 1st generation students. However, as the table shows above, the p-values are not strong enough to state this definitively.
Due to there being only 14 Black students, statistical analyses cannot be done with any significance. Below shows both the count and percentage of Black students in each of the Advantaged Features. It shows the count of students at the bottom (Blacks Total = 14. Other Total = 196.). P-values are not shown on the chart. At the top of the bar it shows the percentage of those students who where in the right group of that feature and therefore had an advantage. Note that Black students were more likely to be 1st generation (a disadvantage, with p-value = 0.002, as calculated by a 2-Proportion Z-Test). Another disadvantage that Black students had was a lower overall gpa (p-value = 0.013).
Similarly, one should question whether being a 1st generation college student is a direct correlation to doing poorly in CSS 143.
Advantage Count Mutable#
If we consider race
and 1stgen
to be immutable characteristics and the rest of the features to be mutable, we see a nearly identical performance between Advantage Count and Advantage Count Mutable.
Repeats#
We did not examine how students improved from their first attempt to subsequent attempts. Random sampling showed that they did improve from one attempt to the next. The primary analysis was to see if those two took a class multiple times performed differently from those who did not.
Students who took 142 multiple times did not perform any differently from students who took it only once. We compared students who took the course only once against those that took it 3 times (only 1 student took it 4 times, and only 6 students took it 3 times). While the difference in the mean grade was 0.6, the p-value was 0.29. Perhaps with a great number of students a correlation could be found. The students who took 142 twice had essentially the same performance (but with a slightly higher variance) as those who took it only once.
Students who retook 143 multiple times did not perform any differently from students who took it the first time. However, students who retook the course had a worse mean grade (0.43), and the p-value for determining significance was 0.076.
More details can be seen in the whisker plots and the table below.
Appendix#
Cohenâs d#
Formula for Cohenâs d is:
\(d = (\bar{x}_1 - \bar{x}_2) / \sqrt{(s_1^2 + s_2^2) / 2}\)
\(\bar{x}_1, \bar{x}_2\): mean of sample 1 and sample 2, respectively
\(s_1^2, s_2^2\): variance of sample 1 and sample 2, respectively
Cohen's d
value indicates the number of standard deviations the two groupsâ means differ by.
