number of classes are
​

Answer:

8 classes required. ....

Step-by-step explanation:

because...8×10=80

Answer 2

The number of classes are: 10

We need to know the class interval, which is the range divided by the required number of classes, in order to calculate the number of classes.

Range / Number of classes equals the class interval.

80/10 Equals 8 for the class interval.

We may use this to classify the data into groups because each class interval is 8 as a result. To establish the upper limit of each class, we start with the minimum value and add the class interval.

Class 1: 0-8

Class 2: 9-16

Class 3: 17-24

Class 4: 25-32

Class 5: 33-40

Class 6: 41-48

Class 7: 49-56

Class 8: 57-64

Class 9: 65-72

Class 10: 73-80

To summarise, we would want 9 classes based on a class size of 10 and an 80-value range in order to handle all potential values inside that range.
