Question

construct a frequency distribution using 8 classes (0 - 7).
class limits class boundaries frequency
0 - 0.5 - 0.5 3
1 0.5 - 1.5 5
2 1.5 - 2.5 18
3 2.5 - 3.5 5
4 3.5 - 4.5 5
5 4.5 - 5.5 3
6 5.5 - 6.5 0
7 6.5 - 7.5 1
total

Explanation:

Step1: Sum all frequencies

Add all frequency values: \(3 + 5+18 + 5+5 + 3+0 + 1\)

Step2: Calculate the sum

\(3+5 = 8\), \(8 + 18=26\), \(26+5 = 31\), \(31+5 = 36\), \(36+3 = 39\), \(39+0 = 39\), \(39 + 1=40\)

Answer:

40
