In a relative frequency distribution, the relative frequencies add up to the relative frequencies add up to 1.
- The frequency of a specific occurrence in a statistical experiment is compared to the overall frequency to determine its relative frequency. the proportion of favourable events that actually occur to all conceivable events; frequently used to assess probability. the percentage of a random variable's range that falls within a certain interval when it takes a specific value.
- Because the heights of relative frequency histograms can be translated into probabilities, they are significant. These probability histograms offer a graphical representation of a probability distribution that may be used to assess the probability that specific outcomes will materialise within a given population.

True.........................
