Peer Response

I’m trying to learn for my Statistics class and I’m stuck. Can you help?

For your responses to your classmates (two responses required): Discuss the relationships between the scatter plot, the correlation coefficient, and the linear regression equation for the sample. Comment on the similarities and differences between your correlation and linear regression equation and that of your classmates. Why are there differences since you are drawing from the same population? Did you expect the differences will be large? Why or why not?

Response 1:

The first graph will represent how many females out of a randomly selected group lost weight on a Keto diet in a month. X is the number of females on Keto and Y is the pounds lost in a month. You can see that there is a positive correlation between females who ate Keto and losing weight.
