Data visualization is a crucial aspect of any data analysis or presentation. It allows us to quickly and easily understand patterns and trends in the data and make informed decisions based on this information. One helpful tool for visualizing data is the box and whisker plot, also known as a box plot. This type of
Standard deviation is a measure of how spread out a dataset is. It is calculated by finding the difference between each data point in the dataset and the mean (average) of the dataset, squaring those differences, finding the average of the squared differences (also known as the variance), and then taking the square root of
The range is the difference between the largest and smallest values in a group of observations. To calculate the range, you need to find the dataset’s smallest and largest values. Then subtract the smallest value from the largest value. In the case of the numbers 6, 9, 10, 11, 11, and 14, the range would be
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,
