Explanation Given: The doses of medication in mg are as mentioned below: ( 80 .63, 79 .78, 78 .78, 80 .79, 81 .13, 79 .17, 78 .66, 79 .13 79 .60, 79 .29, 81 .29, 81 .33, 78 .71, 81 .47, 79 .89, 80 .41 80 .01, 79 .46, 78 .84, 79 .26, 79 .58, 79 .47, 80 .60 and 81 .08 ) Procedure used: Steps for constructing the frequency distribution: 1. Define the classes using the class width. 2. For each of the class place the tally marks, if the data value is in the class interval. 3. Count the number of tally marks for each class interval for obtaining frequency. Steps for finding mean of grouped data: 1. Calculate the midpoint by finding the mean of the endpoints of the class. This is denoted by M . 2. Multiply the each of the frequency F with the corresponding midpoint M for each of the class. These values are denoted as ‘Product, FM ’. 3. Calculate the sum of the frequencies which is denoted as n . 4. Calculate the sum of ‘Product, FM ’. 5. Divide the sum of ‘Product, FM ’ with the sum n . Calculation: The width of each of the class interval is 0.49 Place the tally marks for each of the data value within the interval and count all the tally marks for frequency of each class. The frequency distribution is, Class Tally Frequency, F 78.50-78.99 | | | | 4 79.00–79.49 | | | | | 6 79.50–79.99 | | | | 4 80.00–80.49 | | 2 80.50–80.99 | | | 3 81
