What are the branches of statistics?
Statistics plays a main role in the field of research. It helps us in the collection, analysis and presentation of data. In this blog post we will try to learn about the two main branches of statistics that is descriptive and inferential statistics.
What is the importance of statistics?
Statistical knowledge helps you use the proper methods to collect the data, employ the correct analyses, and effectively present the results. Statistics is a crucial process behind how we make discoveries in science, make decisions based on data,
and make predictions

What is the example of statistics?
A statistic is a number that represents a property of the sample. For example, if we consider
one math class to be a sample of the population of all math classes, then the average number of points earned by students in that one math class at the end of the term
is an example of a statistic.

mean, standard deviation, regression, hypothesis testing, and sample size determination
.
How do you understand statistics?
One way to analyze data is called
descriptive statistics
. Here the goal is to calculate quantities that describe our data. Numbers called the mean, median and mode are all used to indicate the average or center of the data. The range and standard deviation are used to say how spread out the data is.
