Does the mode change , if another observation is added to the data in Example ? Comment .

If another observation 61 is also included to the above data what would be the median?

Median of a data, arranged in ascending order 7, 10, 15, x, y, 27, 30 is 17 and when one more observation 50 is added to the data, the median has become 18. Find x and y.

If the maximum value of an observation in the data in example 4 is changed to 8, would be the mode of the data be affected? Comment.

Arithmetic mean of 7 observations was found to be 32. If one more observation 48 was to be added to the data what would be the new mean of the data?

AM of 11 observations is 17.5 and one observation 15 is deleted from the data then the mean of remaining observations is______

When an observation in a data is abnormally more than or less than the remaining observation in the data, does it affect the mean or mode or median? Why?

AM of 8 observations 30.One observation 30 is deleted from the data then the new mean is______

Is there any change in mode, if one or two or more observations, equal to mode are included in the data?

Statement (D): The most frequently occuring value of set of observations is called the mode. Statement (E) : Always mode is exist any given data: Statement (F): Some times there will be no mode for the given data.

The mean of the data set comprising of 16 observations is 16. If one of the observation valued 16 is deleted and three new observations valued 3, 4 and 5 are added to the data, then the mean of the resultant data, is
