Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): For calculating Arithmetic mean, when Cumulative frequencies are given, the frequencies are to be found for the given series or variables.
Reason (R): Cumulative frequencies are calculated by adding the frequencies.
Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): Arithmetic mean is affected by the extreme values.
Reason (R): All the values are considered while calculating the mean and so if there are more big values or small values it will affect the calculation of the mean.

Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): Combined mean is calculated by multiplying the means with their respective frequencies total and then added and divided by the total number of items.
Reason (R): In weighted mean, the weights are assigned to the respective items in the series and then the mean is calculated.
Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): Fisher ’s Index Number is considered the most ideal index.
Reason (R): Ideal index number is the best way of calculating index number.
Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): The Index Number shows the change in the relative price from the base year.
Reason (R): Index number is calculated as a ratio of current price with the base price.
Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): Index number and Mean are one and the same thing.
Reason (R): Mean is the central value of the items present in the series.
Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): Rahim calculated the value of median to be 16 in the series, 5, 8, 15, 16, 25, 45, 80. He used the formula of odd numbers in this case.
Reason (R): Median for odd series is calculated by the formula (n+1/2)th term.
Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): While calculating Median of the series, the terms need to be arranged in either ascending order or descending order.
Reason (R): In median, the central term is to be found which divides the series into two equal parts.
Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): Median is a positional average.
Reason (R): Median is the centre most item in a series arranged in either ascending order or descending order.
Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): Scatter Diagram method is a graphic expression of the degree and direction or absence of correlation.
Reason (R): Scatter Diagram method fails to produce definite trend.
Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): When correlation coefficient (r) is between +0.75 and +1, high degree of positive correlation and when it is between –0.75 to –1 high degree of negative correlation.
Reason (R): The value of correlation lies between + 1 and – 1.
Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): Less than or more than ogive can be used to calculate correlation.
Reason (R): When changes in two related variables are in the same ratio, then it is a case of perfect correlation.
Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): Mode is affected by the extreme values.
Reason (R): In mode, total cannot be obtained.
Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): Mode of a series 2, 4, 2, 5, 6, 2, 3, 8, 9, 2, 5, 10 is 2.
Reason (R): Mode of a set of observation is that value which occurs the greatest number of times, i.e., with the highest frequency in a series.
Direction: In the following questions, a statement of Assertion (A) is followed by a statement of Reason (R). Mark the correct choice as:
Assertion (A): Mode is dependent on frequencies.
Reason (R): Mode has very less effect of marginal units.
