Answer: Median: 58.5; First Quartile: 55; Third Quartile: 65; Interquartile range: 10
Step-by-step explanation: To find the median, you have to have the data set from least to greatest. Then, you cross out the numbers from left to right until you have one number left. To find the first quartile, you find the median of the numbers that are on the left side of the median. You do the same concept for finding the first quartile. To find the third quartile, you have to find the median of the numbers on the right side of the median. To find the interquartile range, you have to subtract the first quartile from the third quartile. In the future, for the mean, you just find the average of the data set. Hope this helps!!
