WebApr 3, 2024 · We can see that the lower boundary of the previous class interval is equal to the upper boundary of the next class interval, which makes the given distribution table continuous. Let us first find the mean of the given frequency distribution. WebJun 21, 2024 · Exclusive series is the most common one, where we have class intervals like; 0-10, 10-20, etc. Inclusive series is the one where the class intervals are like; 0-9, 10-19, 20-29, etc. We can find the arithmetic mean using inclusive series directly, but sometimes it is asked to convert it into exclusive series and then find the arithmetic mean.

WebMar 8, 2024 · Upper class boundary = (upper-class limit of the concerned class + lower class limit of the subsequent class)/2. For the nonoverlapping class intervals, The actual lower limit = lower limit – ½ x gap. The actual upper limit = upper limit + ½ x gap. Class Limit. The class limit can be defined as the minimum and maximum values contain in a ... WebThe class mark is considered to be the representative value for all the grouped data in a class interval. For example, the values of 81.2 81.2 and 84.6 84.6 are entered in the class 80 80 to 85 85. If the values are to be used for some computation (like computing mean), then instead of the actual values, the class mark 82.5 82.5 is used in ... income tax loss from house property

WebThe middle value of the given data will be in some class interval. So, it is necessary to find the value inside the class interval that divides the whole distribution into two halves. In this scenario, we have to find the median class. To find the median class, we have to find the cumulative frequencies of all the classes and n/2. WebClass Interval = Upper bound limit – Lower bound Limit Class Interval = 49 – 40 Class Interval = 9 Hence proven that the class interval of each class is 9.
