WebThe formula for determining class intervals is as follows: i ≥ (H − L) / k Where: i is the class interval, H is the greatest observed value, L is the smallest observed value, k is the number of class intervals. Generally, 5 ≤ k ≤ 15. You can use Sturges' rule as a guide: k = 1 + 3.322 log10 (n) , where n = number of observations.

WebMedian Class: It is the class where middle position is located. In other words, the class where the half of the cumulative frequency or sum of frequencies lies is called the median class. The median class interval is the corresponding class where the median value lies. To find the median of ungrouped data, we must use the following formula ... WebIf we consider the interval 20-30 as the median class and use the above formula, then the median will be. 20 + 25 2 − 7 5 × 10 = 31. Interestingly, considering the interval 30-40 as …
WebThe cumulative frequency for the first row is 10 and for the second row is 22. The second row passes the the 15th and 16th value so the median must be in there. The median is therefore within... Web\(f\) represents the corresponding frequency of the median class interval; \(h\) represents the width of the median class interval.
