using matlab

the data is labeled Year, Month, Temp.

this is what the imported data looks like X is year Y is month 1-12 Z is Temperature.

I dont know what else I could include in this for help.

4. Evaluation Details: Use the monthly mean temperatures for Norfolk for years from 1874 to 2018 contained in the file NorfolkMonMean Temp.dat. The file has 3 columns (year, month, temperature (F)) separated by spaces. 1. [7:57 Extract the monthly means for January and July. Calculate the average temperature difference (July-January) for Norfolk. Plot the two monthly temperatures vs year on the same plot. Add two lines showing the mean for each month on the same plot. Add appropriate labels and a title. 2. 12;3] Calculate the average temperature for each of the 12 months. Plot the average temperatures for each month for Norfolk vs the month number. Identify the warmest and coldest months with an indicator on the plot. Add appropriate labels and a title. 3. [1:2] For each month, calculate the difference between the monthly average for that year and the average for that month over all years. Calculate the average of the absolute value of the differences (this is the 1- norm of the list) for each month. Plot these average absolute differences for each month. Identify which months have the largest and smallest variability from the long term mean. Add appropriate labels and a title.
