WebJan 8, 2024 · Class-10 Maths Chapter-15, Statistics How to find missing frequencies when median of the data is given. If the median of following data is 32.5, Find the missing frequencies. WebSolution We prepare the cumulative frequency table, as shown below: Now, f1+f2+31 =40 ⇒ f1+f2 =9 ⇒ f2 =9–f1 ....... (i) The median is 32.5 which lies in 30 – 40. Hence, median class = 30 – 40 Therefore, l = 30,N /2= 20,f = 12,and cf= 14+f1 Now, M edian= l+((N /2−cf)/f)×h 32.5 =30+((20–(14+f1))/12)×10 ⇒ 32.5 =30+((6–f1)/12)×10 ⇒ 2.5 … jesd204 transceiver

WebApr 6, 2024 · Hint: In this question, we are given a table with class interval and frequency. The median of the data is also given. Using the median, find the median class. Draw the table calculating cumulative frequency. Use the median class and formula, Median $ = l + \left( {\dfrac{{\dfrac{n}{2} - cf}}{f}} \right)h$ to find ${f_1}$ . lamiran sandals
