## What is class interval example?

The class interval is the difference between the upper class limit and the lower class limit. For example, the size of the class interval for the first class is 30 – 21 = 9. Similarly, the size of the class interval for the second class is 40 – 31 = 9.

What is a class interval of 10?

As we know, class interval = upper limit – lower limit. So, for 0-10, upper limit = 10 and lower limit = 0. Hence, class interval = 10-0 = 10. Similarly, for all classes, 10-20, 20-30, 30-40, 40-50, 50-60.

How do you solve for class intervals?

Class Interval = Upper-Class limit – Lower class limit. In statistics, the data is arranged into different classes and the width of such class is called class interval.

### What is the class interval length of 70 74?

Each class interval is represented by a lower limit (e.g., 95 for the top interval) and an upper limit (e.g., 99 for the top interval)….

Real Limits Apparent Limits Frequency
74.5-79.5 75-79 1
69.5-74.5 70-74 3
64.5-69.5 65-69 2
59.5-64.5 60-64 0

What is class interval in math?

Definition. In maths class interval is defined as the difference between the upper class limit and the lower class limit. The size of the class into which a particular data is divided. E.g divisions on a histogram or bar graph.

How many class intervals are there?

For most data, 6 to 15 classes are enough. Class intervals (lengths) should be equal. Intervals such as 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50, etc are desirable.

#### What is the class size of 40 to 60?

Class Frequency
40-60 10
60-80 f2
80-100 7
100-120 8

What is the class interval of 60 69?

What are the types of class interval?

When dealing with a large set of data values it is convenient to divide the data into intervals of equal length called class intervals. The class intervals formed are of two types – Inclusive Class Intervals and Exclusive Class Intervals.

## What is the class size of 25 35?

Answer: Class Mark of 25 – 35 is 30. Class mark is the average of the limits of the class interval.

What is the class width of class interval 60 to 70 70 to 80?

What is the upper class limit for class 25 35 A 25 B 35 C 60 D 30?

35
Since the upper-class limit for the class 25−3525−35 is 3535.

### What is the frequency of the class interval 10 15?

Class-interval: 10−15 20−25
Frequency: 30 75

What is the upper class limit for the class 25 35 answers?

What is the upper class limit for the class 45 50?

Answer: 50 is the upper limit of the class.

#### What is the upper class limit for the class 25 30?

What is the class mark of class 25 35 A 25 B 35 C 60 D 30?

What is the lower class limit of the class interval 35 39?

\$35
Here, we are given the class interval as \$35 – 39\$, which means the lower limit of this class interval is \$35\$ and the upper limit of the class interval is \$39\$. We need to find the class mark for this class interval. Hence, the class mark is 37.

## What is the class size of 40 60?

10

Class Frequency
40-60 10
60-80 f2
80-100 7
100-120 8

What is the lower limit of the class interval 35 to 40?

Answer: Lower limit is 35 and upper limit is 40 for the given class interval 35-40.
