Explain and give examples of statistics
Statistics is a branch of mathematics that deals with the collection, analysis, interpretation, and presentation of data. It is used to draw conclusions and make decisions based on the data.
Examples of statistics include:
1. Mean: The mean is the average of a set of numbers. For example, if you have the numbers 1, 2, 3, 4, and 5, the mean would be 3 (1+2+3+4+5 = 15, 15/5 = 3).
2. Median: The median is the middle number in a set of numbers. For example, if you have the numbers 1, 2, 3, 4, and 5, the median would be 3 (the middle number).
3. Mode: The mode is the most frequently occurring number in a set of numbers. For example, if you have the numbers 1, 2, 3, 4, and 5, the mode would be 5 (it occurs the most).
4. Range: The range is the difference between the highest and lowest numbers in a set of numbers. For example, if you have the numbers 1, 2, 3, 4, and 5, the range would be 4 (5-1 = 4).
