Standard deviation is a statistical measure that quantifies the amount of variation or dispersion in a set of data values. A low standard deviation indicates that the data points tend to be close to the mean, while a high standard deviation indicates a wider spread around the mean.

Standard Deviation

Standard deviation

A statistical measure is a value that represents a characteristic of a dataset, providing insights into its distribution, central tendency, or variability. These measures are essential for summarizing data, making comparisons, and drawing conclusions in research and data analysis.

statistical measure

Variation refers to the differences or deviations in characteristics among individuals or groups, often within a specific population or dataset. It is a fundamental concept in fields such as biology, statistics, and economics, where it helps in understanding diversity, predicting outcomes, and optimizing processes.

variation

Dispersion refers to the spread of values or data points in a dataset, indicating the extent to which they deviate from the average or mean. It is a crucial statistical measure that helps in understanding the variability, reliability, and consistency of the data being analyzed.

Data points are individual units of information collected and used for analysis, often represented as values or measurements in a dataset. They are crucial for identifying trends, making predictions, and driving decision-making in various fields such as science, business, and technology.

The mean, often referred to as the average, is a measure of central tendency that is calculated by summing all the values in a dataset and dividing by the number of values. It provides a useful summary of the data but can be heavily influenced by outliers, making it less representative in skewed distributions.
