Key Concepts

Descriptive Statistics

Descriptive statistics involve summarizing and organizing data in a meaningful way, such as through measures of central tendency (like the mean), dispersion (like range and standard deviation), and graphical representations. These statistics provide a clear summary of the key features of a dataset, facilitating easier interpretation of data.

Sample Mean

The sample mean is a measure of central tendency that represents the average value of a set of observations in a sample. It is calculated by summing all the observations and dividing by the number of observations, and it serves as an estimate of the population mean when the sample is representative.

Likert Scale

A Likert scale is a popular psychometric scale commonly used in surveys to capture the intensity of respondents' attitudes, opinions, or behaviors on a symmetric agree-disagree scale. It provides a simple way to quantify subjective data by assigning numerical values to qualitative responses.

Random Sampling

Random sampling is a statistical method where each member of a population has an equal chance of being selected for a study. This technique helps to ensure that the sample is representative of the overall population, which in turn allows for more generalizable conclusions about the population based on the sample data.
