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.

- Determine whether the statement is true or false. If it is false, rewrite it as a true statement. The midpoint of a class is the sum of its lower and upper limits divided by two. Choose the correct answer below. OA. The statement is false. A true statement is "The midpoint of a class is the class frequency divided by the sample size." B. The statement is false. A true statement is "The midpoint of a class is the average of its lower and upper limits." OC. The statement is false.
