PPT-Mean, Median, Mode, and Range

Objective You will solve word problems involving measures of central tendency 6SP3 Recognize that a measure of center for a numerical data set summarizes all of its values with a single number while a measure of variation describes how its values vary with a single number . Mean Arithmetic Mean To calculate the arithmetic mean of a set of data we must 64257rst add up sum all of the data values and then divide the result by the number of values Since is the symbol used to indicate that values are to be summed see Sigm Mean, Median, Mode are all types of average. An average summarises groups of data.. Mean. Average often means the ‘mean’. Mean = total of the numbers divided by how many numbers..

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. .
