Given information
Total number of Students= 150
Frequency, Relative Frequency, and Cumulative Relative Frequency are different in respect of Researcher A and Researcher B.
Step-by-step explanation
Step 1.
The sample size is mainly determined by the sample design, required accuracy of estimates, and resource constraints. For a particular design, the sample size can be determined by the level of accuracy required or confidence interval. The more variable the population, the greater the uncertainty will be in our estimate. Similarly, the larger the sample size the more information we have and so our uncertainty reduces.
A good sample should be a representative subset of the population we are interested in studying, therefore, with each participant having an equal chance of being randomly selected into the study.
