Min, Max and Range
In statistics, the minimum, maximum, and range are important measures used to describe the spread of data. The minimum is the smallest value in a dataset, while the maximum is the largest value. The range, which is the difference between the maximum and minimum values, provides a simple measure of variability in the data. While…

Standard Deviation
Standard deviation is a statistical measure that quantifies the amount of variation or dispersion in a set of values. In simpler terms, it indicates how much individual data points in a dataset deviate from the mean (average) value. A low standard deviation means that the data points tend to be close to the mean, whereas…

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…
