Finding the Median
Consider the following set of numbers: 7, 13, 3, 5, 11, 4, 2. Calculate the median of this data set.
Finding the Mean (Arithmetic)
A survey of 5 people was conducted to find out how many books they read in a month. The results were: 3, 4, 8, 1, and 6. Calculate the mean and standard deviation.
Finding the Mode
Given a data set {5, 2, 9, 3, 5, 8, 5, 7, 2}, find the mode of the set.
Finding the Standard Deviation
A random sample of 5 data points, 4, 6, 8, 10 and 12, was collected. Find the standard deviation of this sample.
Finding the Minimum
We have the data set {2,4,9,3,5,7,8,12,15,18}. Calculate the range, variance, and standard deviation, and then find the minimum among these calculated values.
Finding the Maximum
Given the dataset {5, 10, 15, 20, 25}. Calculate the maximum dispersion of the data set.
Finding the Lower or First Quartile
Consider the dataset [3, 5, 7, 8, 9, 11, 13, 15, 17, 19]. What is the first quartile (Q1) of this data set?
Finding the Upper or Third Quartile
Given the data set {3, 7, 8, 5, 12, 14, 21, 13, 18}, find the upper or third quartile (Q3).
Finding the Five Number Summary
Given the following set of data {7, 9, 13, 15, 16, 20, 21, 23, 24, 25, 29, 30, 31, 32, 33, 34, 36, 38, 43, 50}, find the five number summary (minimum, first quartile, median, third quartile, maximum).
