The test scores of students are listed below. 41 45 46 53 57 59 63 68 69 70 71 74 74 75 79 80 82 83 92 92 95 Construct a histogram for the data set. What is the most appropriate measure of variation for this distribution and what is its value? Why did you use this measurement? The interquartile range (IQR) is the most appropriate measure and it is equal to 54. I used the IQR because the graph is skewed. The variance is the most appropriate measure and it is equal to 229.51. I used the variance because the variance is the best measure of variation regardless of the shape of the distribution. The standard deviation is the most appropriate measure and it is equal to 15.52. I used the standard deviation because the graph is skewed. The standard deviation is the most appropriate measure and it is equal to 15.52. I used the standard deviation because the graph is approximately bell-shaped and symmetric. The interquartile range (IQR) is the most appropriate measure and it is equal to 23. I used the IQR because the graph is approximately bell-shaped and symmetric.
