Participant1. What does the correlation coefficient suggest about the link between social anxiety and study hours?
The correlation coefficient is strongly negative being 0.01 which shows that where study hours increase, social anxiety decreases (r= -0.884, p <0.001).
2. Is the relationship statistically significant?
The relationship is statistically significant because the p value is 0.001 which is less than 0.05 making the relationship significant
3. Does attendance level predict whether a student passed?
there is no association between attendance level or passing4. Which result would you prioritize when designing academic interventions?
I would prioritize study hours improving attendance because of it has a strong correlationJune 6, 2025 at 1:50 pm in reply to: Optional Activity 2 – Descriptive Statistics and Exploratory Analysis #8436Ftwniecey
Participant1. Which variables had the most variability ?
GPA – MEAN:3.89 Social Anxiety-MEAN:9.39
MEDIAN:36.50 MEDIAN:3.35
SD:3.86 SD:9.39
MIN:2.70 MIN:20.00
MAX:3.90 MAX:50.00
This indicates that social anxiety had the most variability2. What patterns (if any) can be observed between social anxiety and GPA
The correlation between social anxiety and GPA was quite negative from my observation from the scotter plot I created
Students with High Social anxiety tend to have Decrease in GPA while students with a lower Social Anxiety will have an increase or high GPA
3. Are they any outlines in GPA and Social anxiety Scores
All values fell within the expected range therefore I conclude that there are no outliners4. Do GPA Scores Differ Consistently across years?
From the boxplot that I created it indicated to me that over the 4 year period the GPA scores started to increase in numbers starting from 2.75 in year one to at least 3.75 in the fourth year

3. Is there a relationship between stress and sleep what does the correlation suggest?
There was a strong negative correlation of (-0.97) between PSS Score and Sleep hours
Making it negative 0.001 Showing as one variable Increase the other one decreases -
