• The average value

In the formula for the median of ungrouped data, what does N represent?

• Total frequency

• Total number of items

• Number of classes

• Cumulative frequency

What is the formula for the median in a discrete series?

• M = N+1

• M = N/2

• M = N-1

• M = (N+1)/2

In a grouped data set, what does c.f. stand for?

• Count frequency

• Sum the frequencies

In the continuous series formula for median, what does 'f' represent?

• Frequency of the preceding class

• Frequency of the total class

• Frequency of the succeeding class

• Frequency of the median class

What is the formula for the median in a continuous series?

• M = L + (c.f./N)

• M = L + (f/N)
