In Class IX, you have studied the classification of given data into ungrouped as well as In this chapter, we shall extend the study of these three measures, i.e., mean, median and mode from ungrouped data to that of grouped data. We shall also discuss Let us apply this formula to find the mean in the following example.
Mean, Median and Mode. Introduction. Measures of central tendency, or averages, are used in a variety of contexts and form the basis of statistics. Mean (Arithmetic Mean). To calculate the arithmetic mean of a set of data we must first add up (sum) all of the data values. (x) and then divide the result by the number of values

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. Step 3: Find the median by using the following formula: M edian. ?. ?. ?. ?. ?. ?.
824 250 a) What is the mean salary? To find the mean of data in a frequency table: for each row - multiply each value For grouped data, we use the midpoint of each interval. The following table shows the number of hours per day To get the mean, use this formula: fx. ? n where f is the frequency, x is the midpoint of
Median for Grouped Data. The median for grouped data can be found either by interpolation or by using a formula. The formula is. Median = + (. 1. 2. ?? . . ) where. is the lower boundary or limit of the class containing the median. is the width of the median class interval. is the total
A. Linda needs to estimate this year's tape rentals for a bank loan application. She will use the page 4 tape rentals summarized with a frequency distribution to estimate average daily rentals for the year. B. Linda must calculate each class midpoint and then multiply it by the class frequency. The midpoint formula is.
Practical.3. Measures of central tendency – mean, median, mode, geometric mean and harmonic mean for grouped data. Arithmetic mean or mean. Grouped Data. The mean for grouped data is obtained from the following formula: Where x = the mid-point of individual class f = the frequency of individual class. N = the sum of
