Which measure of central tendency will best convey how often the students typically eat out?. Possible Answers: Mean, Median, or Mode. The Scenario. Mean. : The arithmetic average. Add up all of the values and divide by the number of scores.. 4.2 Shapes of Distributions. Number of Modes. One way to describe the shape of a distribution is by its number of peaks, or modes.. Uniform distribution—has no mode because all data values have the same frequency.. Mode. Statistical analysis involves many mathematical operations which depends on how our variables are measured. Using number 1 to represent “Female”: 1 here is only the symbol.. Using number 1 to represent the only one child in the family: 1 here means real quantity.. First, arrange the numbers in order by size!. Example: 3, 5 , 5, 6, 8, 10, 12. MEAN. The average of the numbers.. Add the numbers together..
