3.Using the annual salaries data set find the range the variance and standard deviation then interpret the meaning of each measure of variation range variance standard deviation with respect to annual salaries 4 if the sample annual salary for Dallas is changed by adding the data point 72.3 compute the mean5.based on the change what valid conclusion can be drawn between means 6.how does the additional data point affect the median please provide an explanation to support your inference

Measures of Central Tendency and Variation A measure of central tendency is a value that represents a typical, or central, entry of a data set. The three most commonly used measures of central tendency are the mean, median and mode, A way to measure the variation (or spread) of a data set is to find the range, variance and standard deviation.
