  • It could describe the entire population or a sample from the population.
  • There are two types of descriptive measures: measures of central tendency and measures of variability
  • Central Tendency: Mean, mode, Median
  • Measure of Viability: Standard Deviation, Variance, Range, Interquartile range

Inferential Statistic:

  • It s the process of estimating population parameter with the help of a sample from the population.
  • A random sample from the population is used to describe the population with the help of sample statistic.
