Question

Each of the following three datasets represent IQ Scores for three random samples of different sizes. The population mean is 100 population standard deviation is 15. Compute the sample mean, median and standard deviation for each sample size

6) Sample Size 5 106 92 98 103 100

Answer 1

Since we know that

Since we know that
Median for a list of even number of data point is the mean of 2 middle most values if we sort the list in increasing order while for a list of odd number it is the middle most value if the list is sorted in increasing order.
Since our list have odd number of data points, this implies that
Median = 100.0

Since we know that
