CHECK POINT 21.Name the three measures of central tendency?a.meanb.medianc.Mode 2.Name the three measures of variability?a.Range b.Variance c.Standard deviation 3.Which measure(s) of variability is expressed in the same unit as the variable? Why is thatimportant?The measure of variability that is expressed in the same unit as the variable is the standard deviation, because the measure of variability is in the same units, it allows for easier interpretation and comparison with the mean and individual data points.4.Test scores for a spelling test are as follows: 85, 90, 70, 80, 55, 80, 78, 92, 79, 85, 73, 88,85a.Calculate all threemeasures of central tendencyb.Calculate all threemeasures of variabilityMean – 80Median – 80Mode – 85Range – 37Variance – 96.83Standard deviation – 9.84
