Mode Calculation for Student Marks Data
The question asks to find the mode of the given marks scored by 10 students. The mode is defined as the value that appears most frequently in a data set.
Given Data Set
The marks scored by the 10 students are:
- 17, 19, 12, 20, 19, 14, 15, 18, 19, 14
Frequency Count
To identify the mode, we determine the frequency of each distinct mark:
- 12: Appears 1 time
- 14: Appears 2 times
- 15: Appears 1 time
- 17: Appears 1 time
- 18: Appears 1 time
- 19: Appears 3 times
- 20: Appears 1 time
Identifying the Mode
By examining the frequencies, the mark 19 occurs most often (3 times). This is higher than the frequency of any other mark in the data set.
Therefore, the mode of the given data is 19.
