A bowler has taken wickets : 0, 3, 2, 1, 5, 3, 4, 5, 5, 2, 2, 0, 0, 1, 2. Find mode.
2
The mode is the value that occurs most frequently in the data set.
Counting each value: 0 appears 3 times, 1 appears 2 times, 2 appears 4 times, 3 appears 2 times, 4 appears 1 time, 5 appears 3 times.
The value 2 occurs the maximum number of times, that is, 4 times.
So the mode of the given data is \(2\).
If the mean of the data is 11, find Z : 3, 21, 10, 7, 6, 9, (Z + 6), 15, 20
The median of the data 10, 15, x, 25, 30 is 20. Find x.
The mean of 10 observations is 25. If one observation is removed, mean becomes 24. Find removed value.
A random sample of 20 people is classified in the following table according to their ages:
Age | Frequency |
15 – 25 | 2 |
25 – 35 | 4 |
35 – 45 | 6 |
45 – 55 | 5 |
55 - 65 | 3 |
What is the mean age of this group of people?
The median of the following observations 46, 64, 87, 41, 58, 77, 35, 90, 55, 92, 33 is 58. If 92 is replaced by 99 and 41 by 43 in the above data. The new median is:
If the difference of mode and median is 36, then the difference of median and mean is:
In a Mathematics test 15 students scored 80 marks, 20 students scored 75 marks, 28 students scored 65 marks and 25 students scored 60 marks, mode of the score is:
If the mode of the scores 10, 12, 13, 15, 15, 13, 12, 10, x is 15, then what is the value of x?
