Descriptive statistics is a subset within statistics that allows You to describe (or explain) and summarize the data you collect and then present it
in an efficient and meaningful way.
Descriptive statistics allows you to Organize, display, and describe data using data visualizations, which can turn
difficult-to-understand variables across a large dataset into bite-sized descriptions.
Descriptive statistics will allow you to Quantitatively and qualitatively describe the main features of a collection of
information, such as where the middle of the data is, how spread out it is, and
where clumps of values or anomalies may exist.
A single value from a dataset can carry plenty of meaning, Compared to a larger dataset (such as your math test score when compared to the
but it can mean even more when scores of the entire class).
Measures of central tendency are used to Indicate and describe the central position of a group of data. These measures are
important because they help you condense data, find representative values, make
comparisons, and perform further statistical analysis.
The three measures of central tendency are mean, median, and mode.
Mean (often referred to as average) is the sum of all values divided by the number of
values in the dataset.
Median Is the middle value that separates the higher half from the lower half of a dataset.
Mode Is the value in a dataset that appears most frequently.
It is the most popular measure of central tendency It uses every data point in its calculation. Mean is calculated using the following
because formula:
Mean=Sum of All Values/Number of All Values
