For the following set of scores: 1, 5, 7, 3, 4   Assume that this is apopulationof N = 5 scores and compute SS, variance and standard deviation for the population.   Now assume that this is asampleof n = 5 scores and compute variance and standard deviation for the sample.   Explain why the formula for sample variance dividesSSby n – 1 instead of dividing by N.

Find the range, variance and standard deviation of the ff 10, 17, 15, 20, 13, 11, 19, 12, 14, 16 Excel form need

A developmental psychologist is interested in studying how long babies gaze at a photograph of a human face. To test this question, she shows a picture to a sample of six babies and records the length of their gaze in seconds. The data are as follows: 12, 17, 18, 20, 20, 29. Calculate the mean, median, mode, range, variance and standard deviation for the sample.

Refer to the accompanying table, which describes results from groups of 8 births from 8 different sets of parents. The random variable x represents the number of girls among 8 children. Find the mean and standard deviation for the number of girls in 8 births. Click the icon to view the data table. The mean is μ = girl(s). (Round to one decimal place as needed.) The standard deviation is o = girl(s). (Round to one decimal place as needed.)
