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
The mean of five numbers is 30. If one number is excluded, their mean becomes 28. The excluded number is
The ‘less than’ ogive curve and the ‘more than’ ogive curve intersect at
The observations 4, 1, 4, 3, 6, 2, 1, 3, 4, 5, 1, 6 are outputs of 12 dices thrown simultaneously. If m and M are means of lowest 8 observations and highest 4 observations respectively, then what is (2m + M) equal to ?
The mean of the series x 1, x 2… x nis X̅. If x 2 is replaced by λ, then what is the new mean?
The mean of a group of 100 observations was found to be 20. Later it was found that four observations were incorrect, which were recorded as 21, 21, 18 and 20. What is the mean if the incorrect observations are omitted?
