How is a frequency distribution converted to a relative frequency distribution?
The relative frequency of a class is the frequency of the class divided by the total number of frequencies of the class and is generally expresses as a percentage.
How do you find the frequency and frequency density on a histogram when you are only given the class width?
To calculate the frequency density we will simply divide the frequency by the class width.
Does cumulative frequency is the total of all class frequencies up to but not including the frequency of the present class?
No.
Does frequency density divided by class width equals frequency?
No.
What is the mid point of a frequency?
The midpoint of a frequency distribution is the value that divides the distribution into two equal parts. It is calculated by adding the lower and upper limits of a class interval and dividing the sum by 2.
Does the midpoint of a frequency distribution class equal the sum of the lower and upper limits?
No, the midpoint is the result of adding the upper and lower limits in a class and dividing that by 2. Essentially the mid point is the average of the two limits.
How do you find class midpoint?
It is the middle of the class. e.g. 0<l<10 - class midpoint is 5 because it is the middle of the class. e.g. 25<t<50 - class midpoint is 37.5 because it is the middle of the class Midpoint = MIDDLE

Class midpoint in statistics?
It is the midpoint of the class interval. I.e let b=the highest number in the class, a = the lowest number in the class. The midpoint is (a+ 1/2(b-a)).
The following frequency distribution analyzes the scores on a math test. Find the class midpoint of scores interval 40 and ndash59.?

How do you draw a cumulative frequency frequency polygon and a frequency curve?
To draw a cumulative frequency frequency polygon, plot cumulative frequency on the y-axis and the upper boundary of each class interval on the x-axis. Then connect the points with straight line segments, starting from the x-axis at 0 cumulative frequency. For a frequency curve, plot the midpoint of each class interval on the x-axis and the frequency on the y-axis. Then connect the points smoothly with a curve to show the distribution of data.
What is the midpoint of the class 16-19?
17.5
