What information can you obtain about the scores in a regular frequency distribution table that is not available from a grouped table?
Answer to relevant QuestionsDescribe the difference in appearance between a bar graph and a histogram and identify the circumstances in which each type of graph is used. A sample of n = 10 scores has a mean of M = 9. One person with a score of X = 0 is removed from the sample. What is the value for the new sample mean? One sample of n = 12 scores has a mean of M = 7 and a second sample of n = 8 scores has a mean of M = 12. If the two samples are combined, what is the mean for the combined sample? For the following sample of n = 7 scores: 8 6 = 2 6 3 5 a. Sketch a histogram showing the sample distribution. b. Locate the value of the sample mean in your sketch, and make an estimate of the standard deviation (as done in ...Calculate SS, variance, and standard deviation for the following population of N = 8 scores: 0, 0, 5, 0, 3, 0, 0, 4.
