Formula In Finding The Mean Median And Mode Of Grouped Data. The different types of mean are Arithmetic Mean AM Geometric Mean GM and Harmonic Mean HM. It is also termed as mean deviation or average absolute deviation.
To find the Median of groued data we cannot just pick the middle value anymore since the data is divided into class intervals. Finding the Modal Class of the Frequency Table. 2 5 3 2 6 4 2 6 2 8 9.
Like we have the below-provided data set.
Finding the Data Range. A measure used to find how much the values in a data set vary from their mean is called as the mean absolute deviation. Finding the Median Class Interval of the Frequency Table. Now find the population standard deviation using the formula.
