Discrete Data

The nature of data is discrete if there are only a limited number of values probable or if there is a space on the number line between each 2 possible values.  Example, A 5 query quiz is specified in a Math class. The number of exact answers on a student's quiz is an example of discrete data.

In discrete data examples the number of exact answers would have to be one of the following: 0, 1, 2, 3, 4, or 5. there are not an endless number of values, therefore this data is discrete. Also, if we were to illustrate a number line and position each probable value on it, we would see a gap between each pair of values.

Definition of Discrete Data examples:

The discrete data is set of data having limited number of values or data points are called Discrete Data. The differing of the discrete data i.e. sets of infinite number of values is called constant Data. For example Data that can only take certain values. The number of apple in a box (you cannot have the half a student).

Examples: Number of hours prakash time spent for playing in a week this is an example of discrete data as playing period (finite) of ram will be specific.

Solved Examples on Discrete Data:

The table illustrates the set of books by Ravi. What type of graph is suitable to display the data in the table?

We use any type of graph is used to display the data
a. Bar graph
b. Histogram
c. Line graph
d. Stem-and-leaf plot

Solution:
Step 1: The data given in the table is discrete.
Step 2: Bar graphs are used to represent discrete data.
Step 3: So, a bar graph is proper to display the data shown in the table.

Problem for discrete data Examples:

The frequency tables situate for the number of worker and their salaries. Find out the distinction between the numbers of worker receiving a salary of 5000and1500.

Solution:

Step1:  The frequency column in the table specifies the number of worker who gets the particular salary.

Step2: From the table, the number of worker who gets a salary $1500 is 8.

Step3: The number of worker who get a salary $5000is 25.

Step4: The difference between the number of worker who get 5000 and those who get 1500 = 25 - 8 = 17

Step5: So, 17 more workers get a salary 4200 than those who get 3900.
