What will be the class mark of the class interval 2.4-6.6?

Question

Answer

The class mark of the class interval 2.4-6.6 is 6.6-2.4= 4.2
4.2 is the answer...

Answer

Is it 4.5

(6.6+2.4)/2
=9/2
=4.5

class mark = upperlimit +lower limit /2

Answer

The Class Mark of the Class Interval 2.4-6.6

To find the class mark of a given class interval, we need to determine the midpoint of the interval. The class mark represents the average value of the lower and upper limits of the class interval. Let's calculate the class mark for the given class interval of 2.4-6.6.

Step 1: Identify the lower and upper limits
The lower limit of the class interval is 2.4, and the upper limit is 6.6.

Step 2: Calculate the class width
The class width is the difference between the upper and lower limits of the class interval. In this case, the class width is:
Class width = Upper limit - Lower limit
Class width = 6.6 - 2.4
Class width = 4.2

Step 3: Find the midpoint
The midpoint of the class interval can be calculated by adding the lower limit to half of the class width. In this case, the midpoint is:
Midpoint = Lower limit + (Class width / 2)
Midpoint = 2.4 + (4.2 / 2)
Midpoint = 2.4 + 2.1
Midpoint = 4.5

Therefore, the class mark of the class interval 2.4-6.6 is 4.5.

The class mark is a useful measure in statistics as it represents the central tendency of the data in the class interval. It provides a convenient way to summarize and compare data across different intervals.
