Document Summary
A group of researchers are interested in investigating whether there is a relationship between happiness and number of facebook friends. Twenty participants completed a 20-item happiness questionnaire, with higher scores indicating higher levels of happiness. They also reported how many facebook friends they have. The data from the study is shown below. Enter the data into spss and answer the questions given below. The means and standard deviations are, happiness (m = 14, sd = 2. 68) and facebook friends (m = 443. 8, sd = 123. 2): using spss, draw a histogram for number of facebook friends. Comment on the histogram, focusing on whether it is positive or negatively skewed. The histogram for number of facebook friends indicates that the sample data are positively skewed as the distribution is heaped on the left with a longer tail on the right side. Assume a two-tailed test with = . 05.
