Question 1 of 10
1. Question
Construction of cumulative frequency table is useful to determine
Correct
Construction of cumulative frequency table is useful to determine Median. It is the Y axis of the point where, X-axis, i.e. frequency axis is N/2, N is total number of observations.

2. Question
What is the middle most value of the data?
Correct
The median of a set of data values is the middle most value when the data has been arranged in ascending order i.e. from smallest value to the largest value.
Incorrect
The median of a set of data values is the middle most value when the data has been arranged in ascending order i.e. from smallest value to the largest value.

Question 6 of 10
6. Question
For a symmetrical distribution what defines mean?
Correct
If a frequency distribution has a symmetrical frequency curve, then mean, median and mode are equal.
However an empirical relationship exists between mean, median and mode. For moderately skewed data distribution.
For a symmetrical distribution Mean = Median = Mode

8. Question
The abscissa of the point of intersection of the less than type and of the more than type o gives of a grouped data gives its
Correct
The abscissa of the point of intersection of the less than type and of the more than type o gives of a grouped data gives its Median.
Since the point of intersection of the more than type o give and less than type o give gives the median on the x – axis.
Incorrect
The abscissa of the point of intersection of the less than type and of the more than type o gives of a grouped data gives its Median.
Since the point of intersection of the more than type o give and less than type o give gives the median on the x – axis.
Question 9 of 10
9. Question
To represent ‘the more than type’ graphically, we plot the ____________ on the x – axis.
Correct
The lower limit for every class is the smallest value in that class on the hand the upper limit for every class is the greatest value in that class.To represent ‘the more than type’ graphically, we plot the lower limits on the x – axis and cumulative frequency on the y – axis to find the median

10. Question
Which of the following is not a measure of central tendency?
Correct
The most common measures of central tendency are mean, median and mode.
Standard deviation is a measure of the dispersion of a set of data from its mean. It is calculated as the square root of variance.
Hence standard deviation is not a measure of central tendency.
