Topics in Data Processing
1. Statistical Techniques in Data Analysis
- Statistical techniques used to analyse data include measures of central tendency, measures of dispersion, and measures of relationship.
- Measures of central tendency give an ideal representative value of a set of observations.
- Measures of dispersion show internal variation in data, usually around a central value.
2. Mean
- Mean is the value obtained by summing all values and dividing by the number of observations.
- Mean is a simple arithmetic average.
- For ungrouped and grouped data, the methods of calculating mean are different.
3. Median

- Median divides an arranged series into two equal numbers.
- Median is independent of the actual value.
4. Mode
- Mode is the maximum occurrence or frequency at a particular point or value.
