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.. 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..

What is the average number of ears in the world human population?. By Joshua and Matthew. Question 1. One of the answers to the question can you find 5 sets of positive numbers that make the mode < median < mean is ….. 2,2,5,10,11- . We got this answer because we thought that the first 2 numbers had to be identical and small because that would give us a small number as the mode. We then chose the median as 5 and then we thought that the mean had to be more than 5, so we chose 6! Next we did 6 x 5 which equals 30 so then we realised that all of the numbers added together must equal 30. 2 2 5 = 9 and 30-9 = 21 and then we picked 2 numbers which were different that equalled 21. .

The mean is the numerical average of the data set, and we use the mean to describe the data set with a single value that represents the center of the data. Many statistical analyses use the mean as a standard measure of the center of the distribution of the data.. What Is Central You have tabulated your data. You have graphed your data. Now it is time to summarize your data. One type of summary statistic is called central tendency. nother is called dispersio FINDING THE MEAN An important concept that is used in calculating grades, in controlling the quality of products, and in many other situations is the “average” of a set of measurements.
