CSET Multiple Subjects: Subtest 2 - Math Measures of central tendency ANS- Mean/arithmetic mean, median, mode, range Mean ANS- The sum of the data values divided by the number of data values; average Example: 2, 2, 3, 5, 2, 6, 2, 6, 7, 9, 11 (2 + 2 + 3 + 5 + 2 + 6 + 2 + 6 + 7 + 9 + 11)/11 55/11 Mean = 5 Median ANS- -The value in the middle so that there are an equal number of data values to either side of it -To find the median, arrange the data values from smallest to largest, including any repeats, then find the middle value -If there is an odd number of data values, one of the data values will be in the middle -If there is an even number of data values, take the mean of the two middle values Example: 2, 2, 3, 5, 2, 6, 2, 6, 7, 9, 11 2, 2, 2, 2, 3, 5, 6, 6, 7, 9, 11 Median = 5 Mode ANS- -The value repeated most often -In order to have a mode, some score had to be repeated Example: 2, 2, 3, 5, 2, 6, 2, 6, 7, 9, 11 Mode = 2 Range ANS- The difference between the maximum and minimum scores Example: 2, 2, 3, 5, 2, 6, 2, 6, 7, 9, 11 11 - 2 Range = 9 Probability ANS- -The comparison of the total number of favorable outcomes to the number of possible outcomes -Usually expressed in fraction form: total favorable outcomes / total possible outcomes -Can also be expressed as percents or decimal values Plane geometry ANS- The study of shapes and figures in two dimensions (the plane) Solid geometry ANS- The study of shapes and figures in three dimensions
