Rubin, Barry FIGURE A: SAMPLING DISTRIBUTIONS IN STATISTICAL ANALYSIS 1. 2. 3. 4. Enter your height in inches here: _________ Use the provided worksheet on the back to calculate the means of each sample. Transfer the results here: Sample 1 Mean: _______ Sample 5 Mean: _______ Sample 9 Mean: _______ Sample 2 Mean: _______ Sample 6 Mean: _______ Sample 10 Mean: _______ Sample 3 Mean: _______ Sample 7 Mean: _______ Sample 11 Mean: _______ Sample 4 Mean: _______ Sample 8 Mean: _______ Sample 12 Mean: _______ Create a frequency distribution for these sample means. Begin by calculating the range (difference between the minimum and maximum values of the sample means). Then divide the range by 5 to determine an approximate interval width. Begin the first category’s lower limit as the minimum value of your sample means and the first category’s upper limit as the minimum value plus the interval width. Add 0.01 to this number to get the second category’s lower limit. Then repeat the process to get the limits of the succeeding categories until you have the fifth category limits established. FREQUENCY DISTRIBUTION OF MEAN HEIGHTS Category Limits Number of Means _____________ ___ _____________ ___ _____________ ___ _____________ ___ _____________ ___ Create a histogram of the frequency distribution of mean heights using the following grid: 5. Write one or two sentences interpreting the information provided by the above histogram. Then indicate how this exercise has added to your understanding of a sampling distribution.
