PhD (2013) Basic Statistics for Health Science Courses by RALO Mendor, PhD (2013) In table 3, the class site or class width used is 15. 80, 95, 110, 125 and 140 are called the lower class limits while 94, 109, 124, 139 and 154 are called the upper class limits. In the class boundary 79.5-94.5, 79.5 is the lower class boundary 94.5 is the upper class boundary. The class mark is obtained by getting the average of the lower and the upper class boundary which is (79.5+ 94.5)/2-87 for the score 80-94. An accurate class width or class interval can then be obtained by getting the difference between the upper and the lower boundary which is 94.5-79.5 15 for the The range (R) for a grouped data is computed by getting the difference of the highest value of the upper boundary and the lowest value of the lower boundary. For the data given above, the range (R) 154.5-79.5-75. Table 3 is a type of frequency distribution that is useful in calculating other descriptive properties of score 80.94 and so…
