Step 3.1 a) From the Statistics Canada dataset you have chosen, calculate the measures of central tendencies (mean, median and mode) and explain the meaning of each in a paragraph. b) Calculates measures of dispersion (standard deviation, variance, EI - Q3-Q1 Interquartile Range, Z scores, percentiles). c) From all the calculated spread metrics, explain which one would be an appropriate "statistical summary" for this dataset by demonstrating it through your calculations.

The following refer to the following data set: 20 28 44 92 64 48 68 43 86 43 What is the mean (7) of this data set? mean = (Please show your answer to one decimal place.) What is the median of this data set? median = %3D What is the mode of this data set? mode = %3D

The following refer to the following data set: 81.6 127.2 98.4 100.5 95.8 106.2 127.2 108 127.2 117.8 What is the arithmetic mean of this data set? mean = What is the median of this data set? median What is the mode of this data set? mode = %3D

Draw the box-and-whisker plot and give the five-number summary for each data set.
