Key Concepts
- 1Types of data: qualitative and quantitative
- 2Measures of central tendency: mean, median, mode
- 3Measures of dispersion: range, variance, standard deviation
- 4Probability and its applications
- 5Interpretation of statistical diagrams and graphs
Simple Explanation
Statistics helps us make sense of data by summarizing it in useful ways. We can find averages, like the mean or median, to understand typical values. We also look at how spread out the data is using measures like range and standard deviation. This helps us see patterns and make predictions.
Memory Trick
“Remember 'DAMP' for data: Data, Averages, Measures of spread, Probability.”
