Solution Mean Grouped Data Ppt Studypool
Solution Mean Grouped Data Ppt Studypool It is adding the class limits and divide by 2. x= ∑ fx = 8 3 2 = 1 6 .6 4 n 50 median and interquartile range – grouped data step 1: construct the cumulative frequency distribution. step 2: decide the class that contain the median. class median is the first class with the value of cumulative frequency equal at least n 2. A group of university students took part in a sponsored race. the number of laps completed is given in the table below. use the information to: (a) calculate an estimate for the mean number of laps. (b) determine the modal class. (c) determine the class interval containing the median. number of laps frequency (x) 1 5 2 6 – 10 9 11 – 15 15.
Solution Mean Grouped Data Ppt Studypool Multiply the midpoint and frequency for each class to calculate the fx value. 3. use the formula x=fx n, where f is the frequency, x is the midpoint, and n is the total frequency, to calculate the mean. for example, given data grouped into classes with frequencies totaling 30, the mean was calculated to be 73.97. 1 of 16. download now. this document provides steps for calculating the mean of grouped data: 1. make a frequency distribution table with class intervals, frequencies, and midpoints. 2. multiply the midpoint and frequency for each class to calculate the fx value. 3. There are two different formulas for calculating the mean for ungrouped data and the mean for grouped data. let us look at the formula to calculate the mean of grouped data. the formula is: x̄ = Σf i i n. where, x̄ = the mean value of the set of given data. f = frequency of the individual data. n = sum of frequencies. 2. multiply the midpoint and frequency for each class to calculate the fx value. 3. use the formula x=fx n, where f is the frequency, x is the midpoint, and n is the total frequency, to calculate the mean. for example, given data grouped into classes with frequencies totaling 30, the mean was calculated to be 73.97. read more.
