Explanation

Statistics is the study of data, often using numbers to summarize and analyze it.

Common terms:

• Mean (average): sum of values ÷ number of values

• Median: middle value when data is sorted

• Mode: most frequently occurring value

• Range: difference between highest and lowest values

Example:
Data: 2, 4, 6, 6, 10

• Mean = (2+4+6+6+10)/5 = 28/5 = 5.6

• Median = 6

• Mode = 6

• Range = 10 − 2 = 8
