Finding Mean, Mode, and Median of Marks and Students
Data:
Marks: 11-15, 16-20, 21-25, 26-30, 31-35, 36-40, 41-45, 46-50
No. of students: 2, 3, 6, 7, 14, 12, 4, 2
Mean:
To find the mean of a set of data, we add up all the values and divide by the total number of values. In this case, we can use the mid-point of each range of marks to represent the values. The mid-point of 11-15 is 13, 16-20 is 18, and so on.
So, the calculation for the mean of marks is as follows:
((13+18)/2) * 2 + ((23+28)/2) * 3 + ((33+38)/2) * 6 + ((43+48)/2) * 7 = 1725
Total number of students = 48
Mean = 1725/48 = 35.94
Therefore, the mean marks of the students is 35.94.
Mode:
The mode is the value that appears the most frequently in a set of data. In this case, the mark range with the highest number of students is the mode.
From the given data, the mark range with the highest number of students is 31-35, with 14 students.
Therefore, the mode of the marks is 31-35.
Median:
The median is the middle value in a set of data when the values are arranged in order. To find the median of this data, we need to arrange the number of students in ascending order and find the middle value.
Arranging the number of students in ascending order, we get:
2, 2, 3, 4, 6, 7, 12, 14
Since there are 8 values, the median will be the average of the 4th and 5th value, which is (6+7)/2 = 6.5.
Therefore, the median of the number of students is 6.5.
Data:
Marks: 11-15, 16-20, 21-25, 26-30, 31-35, 36-40, 41-45, 46-50
No. of students: 2, 3, 6, 7, 14, 12, 4, 2
Mean:
To find the mean of a set of data, we add up all the values and divide by the total number of values. In this case, we can use the mid-point of each range of marks to represent the values. The mid-point of 11-15 is 13, 16-20 is 18, and so on.
So, the calculation for the mean of marks is as follows:
((13+18)/2) * 2 + ((23+28)/2) * 3 + ((33+38)/2) * 6 + ((43+48)/2) * 7 = 1725
Total number of students = 48
Mean = 1725/48 = 35.94
Therefore, the mean marks of the students is 35.94.
Mode:
The mode is the value that appears the most frequently in a set of data. In this case, the mark range with the highest number of students is the mode.
From the given data, the mark range with the highest number of students is 31-35, with 14 students.
Therefore, the mode of the marks is 31-35.
Median:
The median is the middle value in a set of data when the values are arranged in order. To find the median of this data, we need to arrange the number of students in ascending order and find the middle value.
Arranging the number of students in ascending order, we get:
2, 2, 3, 4, 6, 7, 12, 14
Since there are 8 values, the median will be the average of the 4th and 5th value, which is (6+7)/2 = 6.5.
Therefore, the median of the number of students is 6.5.
