Q2. Compute most appropriate measure of central tendency & dispersion to report the variable “changes in triglyceride level” and address its worthiness?

The most appropriate measure of central tendency is the mean. To calculate mean in excel a simple – “=Auto Sum-Average” can be used. The mean for changes in triglyceride level came out to be 34.25. The most appropriate measure of dispersion is Standard Deviation which can be calculated by the excel formula – “STDEV.S(Select the rows or columns)” came out to be 18.77. Because it takes the outliers—significantly higher or lower numbers—into account, the mean is regarded as the most accurate middle value for a given set of values. This makes it a handy number to give when you're trying to find a neutral number that accounts for both good and bad outcomes. It is essential to comprehend the standard deviation. Although the mean pinpoints the distribution's middle value, it does not show how much the data points deviate from the mean. More data points are farther from the mean when the SD is higher.
