how to get the class mark in statistics

Sagot :

misscheska

Subject: Mathematics

Answer:  

Class mark is the middle value in a class.  

For example, if we have the data which is Midyear test of 45 students in Mathematics 10.  

Midyear test of 45 students in Mathematics Grade 10

Class                         FREQUENCY

40 – 42                                    1

37-30                                    0

34 – 36                                    2

31- 33                                    2

28-30                                   14

25-27                                   15

22 – 24                               5

19- 21                                    6

TO GET THE CLASS MARK FOR EXAMPLE 25-27, the class mark is  

(25+ 27)/ 2 = 26

The class mark of 25 to 27 is 26.  

The following re numerical values that are relevant in dealing with frequency distribution.  

1. Class boundaries- They are often described as the true limits because these are more precise expressions of class limits. The lower boundary of a class is 0.5 less than its lower limits, and its upper boundary is 0.5 more than its upper limit.  

For example;  

In the class 25- 27 , the lower boundary is 25 -  0.5 = 24.5 and the upper boundary is  27 + 0.5 = 27.5  

2. Cumulative frequency -there are two kinds of cumulative frequency for a class. The less than cumulative frequency of a class is found by adding the frequency of a class is found by adding the frequency of the class and the frequencies of the lower class.
