Descriptive statistics is a branch of statistics that involves summarizing, organizing, and presenting data in a meaningful way. It focuses on describing and analyzing a dataset’s main features and characteristics without making any generalizations or inferences to a larger population. There are four types of Descriptive Statistics 1. Measure Central Tendency 2. Measures of Variability 3. Measure of Distribution/Frequency Distribution 4. Measure of Position

Measures of central tendency focus on
the average or middle values of data
sets, whereas measures of variability
focus on the dispersion of data.

5. Measure Central
Tendency
Dr Muhammad Yousuf Ali, PhD Scholarly Communication Consultant ©, Researcher
There are three measure
Central Tendency known as
Mean, Median, Mode.

6. Measure of
Frequency
Distribution
Dr Muhammad Yousuf Ali, PhD Scholarly Communication Consultant ©, Researcher
The Distribution (or frequency
distribution) refers to the quantity of
times a data point occurs.
Alternatively, it is the measurement
of a data point failing to occur.

7. Measure of
Frequency
Distribution
Dr Muhammad Yousuf Ali, PhD Scholarly Communication Consultant ©, Researcher
Frequency Distribution measure through
Count, Frequency and Percentage

8. Measures of
Variability
Dr Muhammad Yousuf Ali, PhD Scholarly Communication Consultant ©, Researcher
Measures of variability (or the
measures of spread) aid in
analysing how dispersed the
distribution is for a set of data.

9. Measures of
Variability
Dr Muhammad Yousuf Ali, PhD Scholarly Communication Consultant ©, Researcher
Measures of variability (or the
measures of spread) are measured
through Range, Variance, Standard
Deviation.

10. Measure of
Position
Types of Descriptive
Statistics

The measure of position determine
through Percentile Ranks, Quartile Ranks

11. Measure of
Position

Descriptive
Statistics

Descriptive statistics enables us to
present the data in a more
meaningful way.

14. Importance of

Statistics

Descriptive statistics represent the
data visualization shape like
Tables, Graph, table, Chart and etc.

15. Importance of
Descriptive
Statistics

Descriptive statistics presents in
very simple form so a lay man can
easily understand the data.
