I need help with this question,

the 9 & moodle.uno.edu 2019 2020 Mean 2828.14 Mean 2753.20 Standard Error 7.35 Standard Error 44.60 Median 2815.44 Median 2746.56 Mode #N/A Mode #N/A Standard Deviation 47.08 Standard Deviation 285.61 Sample Variance 2216.44 Sample Variance 81573.47 Kurtosis 1.09 Kurtosis -0.62 Skewness 0.31 Skewness 0 .33 Range 164.34 Range 1135.83 Minimum 2743.07 Minimum 2237.40 Maximum 2907.41 Maximum 3373.23 Sum 115953.75 sum 112881.21 Count 41 Count 41 7. Explain in a complete sentence: What is the principal difference in these data sets and what circumstance do you think accounts for that? We see that the mean of 2020 is less than the mean of 2019 (2753.20 vs 2828.14). The sum affects the mean. Base on the mean, the rest information is calculated to have the maximum approximation of the return, the volatility, and chart data.
