find mean and median

Ultrasound was used to gather the accompanying corrosion data
on the thickness of the floor plate of an aboveground tank used to
store crude oil, each observation is the largest pit depth in the
plate, expressed in milli-in. 98 40 52 94 55 115 60 70 75 85 125 85

Find
1-Mean
2-Median
3- standard deviation

Definition Definition Middle value of a data set. The median divides a data set into two halves, and it also called the 50th percentile. The median is much less affected by outliers and skewed data than the mean. If the number of elements in a dataset is odd, then the middlemost element of the data arranged in ascending or descending order is the median. If the number of elements in the dataset is even, the average of the two central elements of the arranged data is the median of the set. For example, if a dataset has five items—12, 13, 21, 27, 31—the median is the third item in ascending order, or 21. If a dataset has six items—12, 13, 21, 27, 31, 33—the median is the average of the third (21) and fourth (27) items. It is calculated as follows: (21 + 27) / 2 = 24.
