näytesuuruus
Näytesuuruus refers to the number of observations or individuals included in a sample, which is a subset of a larger population being studied. Determining the appropriate näytesuuruus is a crucial step in research design, as it directly impacts the reliability and generalizability of the findings. A sample that is too small may not accurately represent the population, leading to biased or inconclusive results. Conversely, an unnecessarily large sample can be resource-intensive and may not provide substantial additional benefits.
Several factors influence the calculation of näytesuuruus. These include the desired level of statistical confidence, the
In quantitative research, a larger näytesuuruus generally increases statistical power, which is the ability to detect
