It is calculated by adding the upper and lower limits/boundaries and dividing by two.
But in starting i.e. if you are drawing tables then it is written like for e.g. 0-10 then at starting we should write on 10 and then continue as written above.

It is the midpoint of the class interval. I.e let b=the highest number in the class, a = the lowest number in the class. The midpoint is (a+ 1/2(b-a)).
Class width, from statistics, is the difference between the two boundaries of a class. A class is an interval that includes all of the values in a (quantitative) data set that fall within two numbers, the lower and upper limits of the class. Finally, a class boundary is the midpoint of the upper limit of one class and the lower limit of the next class.
To calculate the class boundary of the first class in statistics, subtract 0.5 from the lower class limit of the first class and add 0.5 to the upper class limit of the first class. This is done to account for the fact that class boundaries fall halfway between the class limits.

The class mark is calculated by finding the midpoint of each class interval in a frequency distribution. To do this, you add the lower and upper boundaries of the class interval and then divide by two. The formula is: Class Mark = (Lower Boundary + Upper Boundary) / 2. This value represents the average or central value of the data within that class interval.
what projects can be made relating statistics to daily life (for class 10)?? what projects can be made relating statistics to daily life (for class 10)??
You cannot. Statistics are not an observational tool.

There are very many summary statistics and the answer depends on which of the ones that are appropriate you are interested in.

Class mark = (10.5 + 17.5)/2 = 14Class mark = (10.5 + 17.5)/2 = 14Class mark = (10.5 + 17.5)/2 = 14Class mark = (10.5 + 17.5)/2 = 14
The term class interval is used in statistics.
