he National Oceanic and Atmospheric Administration, an agency of the United States government) on the average ice concentration of the five Great Lakes (Ontario, Erie, Huron, Michigan and Superior) and Lake St. Clair.
You can find the actual data files here that contain the average temperatures for days of the year that measurements were made for each of the six lakes (during the likely icy months of winter). Data were collected between the years 2010 and 2016 and are in percentages of ice cover. Years are actually winter seasons and span the end of a year and the beginning of the next one.

Each day is numbered 1 to 366, 1 being January 1st and 365/366 is December 31st (accounting for leap years).
It is up to you to extract the file data and put it into MATLAB.
You are to make a report showing results, graphs and conclusions based on data using MATLAB functionality.
Calculatetheaverageicecoverageforeachofthelakes(allwinterscombined),andthe average of all six lakes. Here, 7 averages are to be calculated: one per lake and one average of averages
Explanation / Answer
after taking the data in MATLAB, starting from 1 lake, you can take the average of that lake for the given time span, similarly for all time span. and get the average by dividing them by total days.
ex- for ontario lake , you can take the total of 2010-2011, then for the whole 6 yrs span. then divide by 365*6 i.e. total number of days.
after getting all 6 average, you can sum up and divide by 6 to get the final average.
