Standard Deviation Practice Problems (with answers) 1. Consider the following three data sets A, B and C. A = {9,10,11,7,13} B = {10,10,10,10,10} C = {1,1,10,19,19} a. Calculate the mean of each data set. b. Calculate the standard deviation of each data set. c. Which set has the largest standard deviation? 2.
After you have found all the squared differences, you then find out the average of the squared differences. Find the square root of the result, and you get the standard deviation. Students can use these worksheets and lessons to learn how to calculate the common forms of deviation found within data sets.
1) MEAN: The average of a set of numbers. 2) MEDIAN: The middle number when a list is written in order. If there are two middle numbers, the median is the average of those two numbers. 3) MODE: The most frequent number in a list. In the case of multiple modes, the list is said to have no mode.
The standard deviation is used to tell how far on average any data point is from the mean. The smaller the standard deviation, the closer the scores are on average to the mean. When the standard deviation is large, the scores are more widely spread out on average from the mean.
The temperatures, in oC, at a seaside resort were recorded at noon over a. 10-day period. Calculate the mean and standard deviation. 3. John plays golf with his brother Joe each month. They keep a note of their scores. Calculate the mean and standard deviation and comment on John and Joe’s performance over the year.
Calculate the mean and the standard deviation for the following sets of data. Some help has been given. Mean x = ∑fx ÷ ∑f. Standard Deviation = √ ∑f (x - x)2 ÷ ∑f. Q1. Data = 1, 1, 3, 2, 3, 1, 2, 3, 1, 1, 2, 2, 1, 3, 1. x.
