Question

Orthopedic research has shown that repetitive finger bending beyond 20 degrees when using a computer mouse increases the possibility of getting trigger finger. Each of 18 students at Mars University used a new mouse design and each students finger bending measure in degrees was recorded. The following were the measurements:

24, 22, 27, 24, 21, 24, 23, 25, 24, 22, 22, 28, 22, 23, 21, 24, 21, 25

Finger bending measures in degrees are known to be normally distributed with unknown mean of ? degrees and an unknown standard deviation ? degrees

a) Calculate the sample median for this data.

b) Calculate the sample mean for this data..

c) Calculate the sample standard deviation for this data.

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.
