Term | Definition |
Frequency Distribution | shows how a data set is partitioned among all of several categories(or classes)by listing all of the categories along with the number of data values in each of the categories |
Lower class limits | are the smallest numbers that can actually belong to different classes |
Upper class limits | are the largest numbers that can actually belong to different classes |
Class boundaries | are the numbers used to seperate classes, but without the gap created by class limits .5 1-2 2.5 |
class midpoints | are the values in the middle of the classes that can be found by adding the lower class limit to the upper class limit and dividing the sum by two |
class width | is the difference between two consecutive lower class limits or twio consecutive lower class boundries 60-69 70-79 class width is 10 |
histogram | basically a graphic version of a frquency distribution. horizontal scale: Use class boundries or class midpoints Vertical scale: use the class frequncies |
Relative frequency distribution | includes the same class limits as a frequency distribution, but the frequncy of a class is replaced with a relative frequncies( a proportion) or a percentage frequncy ( a percent) |
cumulative frequncy | It adds up like 60-69 has 5 so anything under 70 has 5 but 70-79 has 5 so anything under 80 is 10 |
