CALCULATING STANDARD DEVIATION 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 standard deviation is calculated to find the average distance from the mean. Practice Problem #1: Calculate the standard deviation of the following test data by hand. Use the chart below to record the steps. Test Scores: 22, 99, 102, 33, 57, 75, 100, 81, 62, 29 Mean: n: (Difference from the mean) (x – x)? Difference from the mean Test Score (x) (x- X) Sum of (Difference from the mean) E(x- X) → This is called variance. Sum of (Difference from the Mean) divided by degrees of freedom (n -1): E(x - x)? (п — 1) Final Step: Standard deviation = square root of what you just calculated (variance). E(x-x)? Standard deviation = (п-1)
K Use the body temperatures, in degrees Fahrenheit, listed in the accompanying table. The range of the data is 3.6°F. Use the range rule of thumb to estimate the value of the standard deviation. Compare the result to the actual standard deviation of the data rounded to two decimal places, 0.67°F, assuming the goal is to approximate the standard deviation within 0.2°F. Click the icon to view the table of body temperatures. The estimated standard deviation is F. (Round to two decimal places as needed.)
