Frequency Distribution
The number which tells us how many times a particular data appears is called the frequency. For example, 2 marks have been scored by five students which means marks 2 occurs five times. Therefore, the frequency of score 2 is five. Similarly, the frequency of mark..

Question : I want to perform a frequency distribution with height for different age classes.
Answer : A frequency distribution describes how often the potential responses occured. The distribution might NOT be simple bell curve. If you had a room full of people, and you counted how many of them weighed less than a 100 lbs, then you counted how many weighed between 100-110, then how many between 110-120, and kept counting until you had counted all the 10-lb groups, you would have a frequency distribution. The distribution is normally displayed by making a bar graph with a bar for each group, in this example, a bar for each 10-lb group. The bar is as tall as the number of people counted in that group.

Question : Just starting this class yesterday and the wording of some problems are really getting to me.
Relative Frequency Distribution: After constructing a relative frequency distribution summarizing IQ scores of college students, what should be the sum of the relative frequencies?
What sum are they talking about? They give no numbers or charts.
Any help is appreciated. :)
Thanks
Answer : A frequency is how many times something happens. For example, I go to burger king 5 days this week. A relative frequency is how many times something happens out of a total number of times. It's expressed as a decimal, fraction, or %. For example, I go to burger king 5 days out of 7 this week. That would be 0.714 or 71.4% or 5/7. A frequency distribution is the complete picture, detailing all the happenings, and the frequencies that each thing happens. For example, I go to Burger King 5 days this week, McDonald's 1 day this week, and Taco Bell 1 day this week. A relative frequency distribution is basically the same as the previous, but it's expressed it as decimal, fraction, or %. For example, Burger King 5/7, McDonald's 1/7, Taco Bell 1/7. In every distribution, the sum of relative frequencies is equal to 1, or 100%. For example, as in the example I gave you, 5/7 + 1/7 + 1/7 = 1. It's a law of probability, so you won't need numbers or charts for this.
