Formula for finding class width
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. WebApr 23, 2013 · More answers. Wiki User. ∙ 2013-04-23 19:26:06. Copy.
