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 \(2\).
The mean of 10 observations is 25. If one observation is removed, mean becomes 24. Find removed value.
The median of the data 10, 15, x, 25, 30 is 20. Find x.
If the mean of the data is 11, find Z : 3, 21, 10, 7, 6, 9, (Z + 6), 15, 20
If X̅ = 20 is the mean of 10 observations x1, x2, ... x10; then what is the value of \(\displaystyle \sum_{i=1}^{10}\left(\frac{3 x_i-4}{5}\right) ?\) ?
What is the mean of the numbers 1, 2, 3, ... 10 with frequencies 9C0, 9C1, 9C2 ..., 9C9, respectively?
Which one of the following measures of central tendency is used in construction of index numbers?
The mean of five numbers is 30. If one number is excluded, their mean becomes 28. The excluded number is
