SAMPLE SIZES Meaning and
Definition
-
Sample sizes refer to the number of observations or participants in a research study or experiment. It is the size of the sample that is selected from the larger population under investigation. Determining an appropriate sample size is crucial in ensuring the validity and reliability of study findings.
To define sample sizes, it is important to consider factors such as the specific research design, the target population, the desired level of statistical power, and the nature of the variables being studied. In quantitative research, larger sample sizes generally increase the representativeness of the sample and enhance the generalizability of the findings to the larger population. However, larger sample sizes can also be more time-consuming and costly to collect and analyze.
Determining an optimal sample size involves striking a balance between the desired level of precision and feasibility. While a larger sample size may yield more reliable results, researchers must weigh it against resource constraints and the practicality of recruiting and collecting data from a larger number of participants.
Sample sizes have a direct impact on statistical power, which refers to the ability to detect effects or relationships between variables. A smaller sample size may reduce statistical power, making it more likely to miss meaningful effects or relationships. Conversely, a larger sample size increases the chances of detecting such effects or relationships if they truly exist.
In summary, sample sizes in research studies indicate the number of observations or participants included in a study. Proper determination and justification of sample sizes are essential for obtaining valid and generalizable results while considering practical considerations such as resources and statistical power.

Etymology of SAMPLE SIZES
The word "sample" originates from the Old French word "essample", which means "an example" or "something that serves as a pattern to be imitated". It then evolved from Middle English "sampil" to the modern English form "sample", referring to a small part or quantity of something taken to represent the entire item or population.
The term "size" comes from the Old English word "siz" or "sise", meaning "an allotted portion" or "a fixed quantity". It later developed into "size" in Middle English, signifying the relative extent, dimensions, or measurements of something.
When combined, "sample sizes" refers to the designated amount or number of items or individuals chosen from a larger population to be studied, tested, or analyzed as a representative subset.
