To analyze the correlation between grades and TEAS scores, we need to focus on the columns representing grades and the TEAS Score. The relevant columns are:

Let's clean the data and calculate the correlation between these grades and the TEAS scores.

The correlation matrix shows the relationship between the grades in various courses and the TEAS scores. Here are some key observations:

Let's visualize these correlations to get a better understanding.

The analysis reveals that grades in various courses have a positive correlation with TEAS scores. The highest correlations are with BIO202 Grade (0.371), BIO201 Grade (0.326), and BIO202A Grade (0.323). The lowest correlation is with BIO203A Grade (0.183). This suggests that better performance in these courses is associated with higher TEAS scores. A bar plot was created to visualize these correlations.
