How To Find Missing Frequency In Statistics
How to find missing frequency if mean is given. I hope it was helpful, you can refer to more posts related to the statistics. H = size of class interval = 10. A student noted the number of cars passing through a spot on a road for 100 periods each of 3 minutes and summarized it in the table given below. Where, l is the lower limit of modal class and in our case, it is 30, h is the class size and is equal to 10, f 0. 3 f 1 + 7f 2 = 252. F 0 = frequency of class preceding modal class=x. M o d e = l + ( f 1 − f 0 2 f 1 − f 0 − f 2) × h. ⇒ 3 f 1 + 7f 2 = 252 → (2) multiply equation (1) with 3, we get. Find the mode of the data.
So, missing frequency is 15. Find the mode of the data. Given that mode = 67. ⇒ 3480 + 30 f 1 + 70f 2 = 6000. H = size of class interval = 10. Bi find the missing frequencies if total frequency is 100 and median is 32 : Of number/items) so, take the sum of all objects and divide it. Is the frequency of class preceding modal class and it is equal to 10, f 1. Σfx/σf = (2060 + 30f 1 + 70f 2 )/50 = 62.8. Then f1+f2 t o al frequency−sum of the given frequency. 2060 + 30f1 + 70f2 = 62.8 (50) 2060 + 30f 1 + 70f 2 = 3140.
