If a coin is tossed once, the probability of getting heads is:

Find the median of the data: 12, 15, 18, 22, 25, 30.

A histogram differs from a bar chart because:

The cumulative frequency of the last class in a distribution is equal to:

If each value in a data set is multiplied by 2, the new mean is:

What is the probability of rolling an odd number on a fair die?

What is the estimated probability based on relative frequency of an event that occurs 35 times in 200 trials?

What is the relative frequency of an event if it occurs 15 times out of 50 trials?

What is the class mark of the interval 25-35?

The total of all frequencies in a frequency distribution equals the:
