# math240 application of correlation

Using the data set provided from the NOAA for Manchester, NH, select any month between January 1930 and December 1958. Use the variables â€œMMXTâ€ and â€œMMNTâ€ for your analysis. Begin with your chosen month and analyze the next 61 data values (i.e. 5 years and 1 month) to determine if a relationship exists between the minimum temperature (MMNT) and the maximum temperature (MMXT).

Using Excel, StatCrunch, etc. create a scatter plot for your sample. Determine the
linear regression equation and correlation coefficient. Embed this scatter plot in your
initial post.

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?
