3. What is simple random sampling?

4. How to conduct simple random sampling To conduct simple random sampling, you will need a list of all the members of the population. This list is called the sampling frame . Once you have the sampling frame, you can use a random number generator to select the members of your sample. There are a number of different ways to generate random numbers. You can use a table of random numbers, a random number generator on a computer , or even a dice roll . Once you have generated a random number, you can then select the corresponding member of the population for your sample.

5. Example of simple random sampling Suppose you want to conduct a survey of students at your college. The population is all the students at your college. You have a list of all the students at your college, which is your sampling frame. To select a random sample of students, you could use a random number generator to generate a list of random numbers. Each random number would correspond to a student on your sampling frame. You could then select the students on your list to include in your sample.

6. There are two main types of simple random sampling: Lottery method: This method is similar to drawing names from a hat. Each member of the population is assigned a number, and then random numbers are drawn to select the members of the sample. Random number method: This method uses a random number generator to select the members of the sample. Each member of the population is assigned a number, and then the random number generator is used to generate a list of random numbers. The members of the population with the corresponding numbers are then selected for the sample.

7. some examples of how to use each type of simple random sampling:

8. Lottery method: Suppose you want to select a random sample of 100 students from a college of 1000 students. You could write the name of each student on a slip of paper and then put the slips of paper in a hat. You would then draw 100 slips of paper from the hat to select your sample.
