Frequency Table
A table that summarizes the occurrence of attribute values or spatial features, supporting statistical and spatial analysis (standard GIS usage).
What is Frequency Table?
A tabular summary of the frequency of each value or range of values in a dataset is called a frequency table. The number of observations, or frequencies, that fit into each category or interval (referred to as a class) is listed.
Frequency tables are used in statistical analysis and Geographic Information Systems (GIS) to comprehend the distribution of characteristics like elevation ranges, population classes, and land cover types. A frequency table could, for instance, display the proportion of pixels in a land use raster that represent urban, forest, or water areas.
This tool facilitates data-driven decision-making by assisting in the identification of patterns, trends, and outliers in data, which facilitates additional analysis and the creation of graphs and charts.

Data can be arranged using a frequency distribution table to display the frequency at which a given value or range of values occurs. By classifying the raw data, it facilitates the identification of trends, patterns, and the dataset's overall distribution.
Data is arranged in a frequency table to display the frequency of each value. List every unique value in a single column, then count and note how many times each value appears in the following column to make one. To illustrate proportions, you can optionally specify relative frequencies or percentages. This makes it simple to quickly identify trends in the data.
Data is arranged into classes or intervals and the frequency of values falling inside each range is displayed in a grouped frequency table. It makes patterns, trends, and distributions easier to understand at a glance by simplifying big datasets.
The frequency of each value in a dataset in relation to the total number of observations is displayed via a relative frequency distribution. It makes it simpler to compare various categories or datasets by expressing frequencies as fractions or percentages rather than raw counts. It is frequently used in statistics to show proportions and patterns in data.
