Descriptive statistics:-we manly study about Describing the data, like mean Mean, mode, median and interquartile range, Visualizing the data by various types of graphs and chart like-Box plots, tables and graphs.

Probability and Probability distributions. -. The chance of something happening,study of data and graphs. eg.-winning an election, normal distribution etc.

Planning and analyzing experiments. Where we study whether we are able to decide if results of studies are valid or not.

Regression analysis and correlation coefficients. Here we work with graphs like scatter plots to fit data to equations to find future trends.

Tables:- we use lots of these in elementary statistics, like the z-table and t-table. These Tables tell us a lot about probabilities of data distributions.
