Topics in Statistics

1

1. Types of Data and Frequency Distributions

  • Ungrouped data is data that has not been organised into groups.
  • Grouped data is data that has been organised into groups.
  • Discrete frequency distribution lists distinct values with their frequencies.
2

2. Measures of Central Tendency

  • A measure of central tendency is a single value that describes the characteristic of the entire data.
  • The main measures are arithmetic mean, median, and mode.
  • Arithmetic mean is the most commonly used representative value.
3

3. Measures of Dispersion

  • Measure of dispersion tells how scattered the data are around a central value.
  • The main measures are range, mean deviation, and standard deviation.
  • Range is the simplest measure of dispersion.
4

4. Properties of Variance and Standard Deviation

  • The sum of deviations of observations from their arithmetic mean is always zero.
  • The sum of squares of deviations about the arithmetic mean is minimum compared with any other value.
  • Variance is independent of the choice of assumed mean a.
