The following table contains data collected on the math averages of seniors in high school and their math averages as freshman i
n college. Make a scatter plot and determine if there is a correlation between the two variables.
1 answer:
For sake of convenience, mark one column in increasing order,then mark both the values on their corresponding axes (as shown in the pic.)
After examining the Scatter Plot, we can say that there is a correlation between two variables like, they are proportional to each other and shows linear function.
