the following are the scores of 50 students in a test. 3.9 2.9 4.4 3.1 4.6 3.7 2.6 3.4 3.2 4.2 3.0 3.5 2.5 1.8 2.6 3.7 1.5 2.2 2.6 2.8 2.1 1.5 4.0 2.5 2.8 3.3 .3.2 2.1 4.3 3.2 3.7 4.7 1.8 3.0 3.7 2.9 4.3 1.4 2.2 3.5 2.8 2.6 3.1 4.1 3.2 4.9 2.4 2.0 3.2 1.4 prepare an 1.appropriate frequency distribution by grouping the score into 6 class 2(a) calculate the mean score (b) the mode (c) the meadian of thr score (d) mean deviation (e) variance (f) standard deviation

Answer 1

mean is the average, mode is # appearing most often, median is the middle number when you order them from smallest to biggest, mean deviation is the first measure of dispersion that we will use that actually uses each data value in its computation.
