LESSON 29 - SAMPLING: METHODS OF DETERMINING THE SAMPLE SIZE IN QUANTITATIVE RESEARCH

In Lesson 28, we have defined a sample is a subset of the population that is chosen for participation in a study. Determining the adequate sample size is the most important decision that a researcher needs to make. Contrary to popular opinion, determination of sample size is a scientific process that requires the researcher to think through it carefully based on the research problem.
This lecture will take you through the five main strategies that a quantitative researcher may use to determine the sample size. Before the strategies, the lesson will also discuss the factors to consider when determining the sample size.

Highly appreciative of this Daktari.

[@patrickkimiti9808]

Thank you Dr Lydia. This presentation on sampling is the first l am watching in the series and l find it very clear. It makes the sampling part of research appear a lot easier to approach and tackle effectively. Hope to to watch the presentations on the other topics. Best wishes,

Thank you so much Dr Lydiah Wambugu , very informative and well explained lesson

[@research-methods-class]

Glad it was helpful!

[@peninahkaromo4082]

Thank you Dr. Lydia.
I would like to know among the three last scientific sampling strategies is there any superior than the other from your experience.

[@research-methods-class]

Hello Peninah. None is superior than the other. The choice of a technique is determined by the research approach you have adopted and the philosophical assumptions

[@blockbusterradio8625]

Hello, nice learning videos.
Thought you could add some revision question at the end of each video so ass to test if one has learned..

[@research-methods-class]

Good suggestion Block. These lessons are meant to offer additional materials or extra resource to what you are learning in your course, so practice your level of understanding by using the revision questions you have in your course

Greetings Doc, you said, the sample size should come from sampling frame, which come as well from accessible population. This one is a subset of target population. We have noticed that the online calculator or mathematics formulae have no provision for accessible population either the sampling frame. Therefore, what is your comment on this?

[@research-methods-class]

Population is determined by the researcher. It's your research problem that dictates the population. The calculator calculates for you the sample from the population you input

[@sashamatope8578]

Hi Dr Wambugu, Thank you for this presentation. I have a question on the population (N). In the case that I'm conducting an online survey where i don't know the population size but i need to come up with a sample....how best can i come with the N. Thank you for your help.

[@research-methods-class]

Thank you for kind comment and the question. Kindly access all the lessons on www.researchmethodsclass.com/research-methods-course/
You assume an infinite population of over 100,000 and the sample size is 384

[@sashamatope8578]

Thank you a lot Dr!

How do I determine the sample size for anc mothers accessing health education in level 5 hospital

[@research-methods-class]

From the population of all the mothers who visit the hospitals
