1. Frequency and cumulative frequency; Question for participation – response needed

Grouped data is data that has been organized into classes. The data that is provided in the major assignment 1 will be ungrouped data and we start the frequency table by organizing into classes(bins). What is the difference between frequency and cumulative frequency? Give an example with a set of data values or create a table explaining the same with or without Excel

2. Bar graph and histogram; Question for participation – response needed

There are mainly two differences between a bar graph and a histogram, one is in the type of data that is presented and the other in the way they are drawn.

3. Question for participation – response needed

Computing weighted averages

Credits	Grade	4.0 scale
4	C	2.0
3	B	3.0
2	A	4.0

Let’s assume a student gets an A, B and a C in the 3 classes. Using a 4-point scale you might assume their GPA is (2.0 + 3.0 + 4.0)/3 = 3.0. But this is incorrect because your G.P.A is weighted by the number of credits each class is worth. In this class, the C is a 4-credit class, B is a 3-credit class and the A only a 2-credit class. So, what would be the correct GPA of this student?
