Descriptive analysis is a data analysis technique used to describe and summarise data from a sample or population. This technique involves the use of statistical measures and graphs to summarise and visualise characteristics and patterns in the data.
Descriptive analysis is commonly used in data exploration, where statistical techniques are used to identify patterns and trends in the data. It is also used in scientific research to describe the characteristics of a sample or population.
Statistical measures used in descriptive analysis include measures of central tendency, such as mean, median and mode, and measures of dispersion, such as variance and standard deviation. Graphs, such as histograms, box plots and scatter plots, are also used to visualise the data and summarise its characteristics.
