Random Sampling: Random sampling is a method of selecting a sample where each individual in the population has an equal chance of being chosen.
Sampling Bias: Sampling bias occurs when certain members of the population are more likely to be included in the sample than others, leading to an unrepresentative sample.
Sample Size: The sample size refers to the number of individuals or objects included in a sample. A larger sample size generally leads to more reliable results and better representation of the population.
