In descriptive statistics, several common variation measurements are used to describe the spread or dispersion of a group of observations. Some of the most common measurements of variation include:Range: The range is the difference between the largest and smallest values in a group of observations. It is a simple and easy-to-understand measure of variation, but it
Quantiles are an important statistical concept that allows us to divide data into equal groups. They are often used to identify and analyze data patterns and make meaningful comparisons between different datasets. In this quick guide, we’ll cover the basics of quantiles and take a closer look at some of the most common types: quartiles,
The median is a measure of central tendency used to describe a dataset’s middle value. The median is the middle value if the dataset has an odd number of values. If the dataset has an even number of values, the median is the average of the two middle values. The formula for calculating the median of
Descriptive statistics is a branch of statistics used to summarize and describe the characteristics of a dataset. Descriptive statistics involves calculating summary measures, such as the mean, median, mode, quantiles (generally quartile), range, interquartile range, standard deviation, and variance and using visualizations, such as histograms and scatter plots, to understand the distribution and patterns in
Descriptive and inferential statistics are two main branches of statistics that are used to analyze and interpret data. Descriptive statistics is a branch of statistics used to summarize and describe the characteristics of a dataset. Descriptive statistics involves calculating summary measures, such as the mean, median, mode, range, standard deviation, variance, inter-quartile range (IQR) and using
