Median
The median is a measure of central tendency that represents the middle value in a data set when it is ordered from least to greatest. Unlike the mean, which can be heavily influenced by outliers, the median provides a more robust indicator of the central location of data, especially in skewed distributions (Smith, 2020). To…

Mode
The mode is a statistical measure that represents the most frequently occurring value in a data set. Unlike the mean or median, which require numerical calculations, the mode can be identified simply by observing which number appears most often. This makes it particularly useful for categorical data where numerical averaging is not possible. For example,…

Mean
The mean, often referred to as the average, is a measure of central tendency that is widely used in statistics to summarize a set of data. It is calculated by summing all the values in a dataset and then dividing by the number of values. This measure provides a single value that represents the center…

Describing Variables Nummericaly (Chapter 4)
Measures of Central Tendency Measures of central tendency are statistical values that aim to describe the center or typical value of a dataset. The three most common measures are mean, median, and mode. Mean The arithmetic mean, often simply called the average, is calculated by summing all values in a dataset and dividing by the…

Univariate Analysis: Understanding Measures of Central Tendency and Dispersion
Univariate analysis is a statistical method that focuses on analyzing one variable at a time. In this type of analysis, we try to understand the characteristics of a single variable by using various statistical techniques. The main objective of univariate analysis is to get a comprehensive understanding of a single variable, its distribution, and its…
