Practice Statistics MCQs from the Mathematics syllabus.
The sum of deviations of 10 values from 20 is 5. What is the mean?
If the mean of 7 observations is 18, and one observation 12 is removed, what is the new mean?
The mode of a distribution is 24 and the median is 20. What is the mean?
What is the mean of first 10 multiples of 5?
For which data set is the mean, median, and mode all equal to 3?
If the mean of 10 observations is 15, and 2 is added to each of first 5 and 4 is added to each of last 5, the new mean is:
In the data 2, 4, 6, 8, 10, if 10 is replaced by 20, which measure changes the most?
The sum of 20 observations is 400. If the sum of first 10 is 150, what is the mean of the last 10?
If $N=100$ and median position is given by $N/2$, what is the position?
If mean is 15, median is 16, then the distribution is:
The mean of 5 observations is 7. If a new observation 13 is added, the new mean is:
If each observation is decreased by 10%, the mean:
In the formula for mode $L + \frac{f_1 - f_0}{2f_1 - f_0 - f_2} \times h$, $f_1$ is the frequency of:
If the mean of two numbers is 5 and their product is 24, the numbers are:
