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 large...
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 th...
ISO 9001:2015 is the latest version of the internationally recognized standard for quality management systems. This standard outlines the requirements for an organization to establish, implement, maintain, and continually improve a quality management...
In statistics, the mode is a measure of central tendency representing the most frequently occurring value in a data set. For example, if we have the following numbers: 10, 11, 14, 9, 6, 10, the mode would be 10 since it is the most frequently occurr...
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 middl...
The mean, or average, is a measure of central tendency used to describe a dataset's typical or average value. To calculate the mean of a dataset, you add up all the values in the dataset and then divide by the number of values. For example, if you h...
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, int...
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 stat...
Sampling is the process of selecting a subset of data from a larger dataset. Sampling is often used in statistics and research to make inferences about a population based on a smaller sample of data. There are several reasons why sampling is essentia...
In statistics, data can be classified as either continuous or discrete. Continuous data can take on any value within a given range, while discrete data can only take on specific values within a given range.Continuous Data:Continuous data, such as tim...
