Review Unit 4AWhat values are used to measure the spread of data?

Answer: Range & IQRReview Unit 4AWhat values are used to measure the center of data?

Answer: Mean & MedianReview Unit 4ACompare the following data sets using spread and measure of center.Data Set A: {20, 22, 24, 27, 28}Data Set B: {35, 40, 42, 34, 34}

Answer: -Data Set B has a higher measure of center because its median is higher than data set A. Median of Data Set A= 24, Median of Data Set B= 35-Data Set B has a greater spread because its IQR is 7 versus the IQR of data set A which is 6.5Review Unit 4AUsing the following frequency chart determine which interval the median would be located in.
