Statistics is a branch of mathematics that involves collecting, analyzing, and presenting data. It also includes drawing conclusions from quantitative data. Statisticians are people who work in statistics.
Here are some examples of statistics:
Average number of points earned in a math class
If a math class is considered a sample of all math classes, then the average number of points earned by students in that class is a statistic.
Percentage of women who believe in global warming
If a survey sample is taken, then the percentage of women in that sample who believe in global warming is a statistic.
Proportion of driver dummies who would have suffered head injuries
If a sample of cars is selected, then the proportion of driver dummies who would have suffered head injuries in that sample is a statistic.
Statistics is concerned with making reliable conclusions about large groups and general events from small samples. The mathematical theories behind statistics use probability theory, linear algebra, and differential and integral calculus.
Some examples of data representation in statistics include:
Bar graph
A group of data represented by rectangular bars where the length of each bar is proportional to the value.
Pie chart
A circle divided into sectors where each sector represents a proportion of the whole.
