Explain about frequency distribution and relative frequency distribution
Answers
Answer:
A frequency distribution shows the number of elements in a data set that belong to each class. In a relative frequency distribution, the value assigned to each class is the proportion of the total data set that belongs in the class. ... For the supermarket example, the total number
Answer:
Frequency vs. Relative Frequency
The terms “frequency” and “relative frequency” usually turn up when we talk about probability in statistics or math. Probability expresses a belief that a certain result will occur in an experiment, test, or research; it is used to determine the chances of a specific event happening. The probability of an event can be determined by conducting a little experiment and doing some minor calculations. Most people use probability in statistics; some use it in other areas of study as well, including mathematics, science, finance, or even gambling.
In statistics, frequency is the total number of times a given result came up in an experiment or study; the total number of times an event occurs. It can be said that frequency simply means the rate of occurrence. For instance, you are going to execute a test to determine the probability of getting a six when throwing a dice. You throw the dice ten times, and the side of the dice with six dots on it shows up three times. The result “three times” is your frequency. Drawing a card from a deck of cards is another way to test probability and to get the frequency at which a heart will be drawn. Pick five cards and see how many you get that have the heart symbol on them. Let’s say you got three heart cards – that is your frequency. You can obtain the frequency immediately after you carry out your experiment without having the need to calculate.
