Important Terms & Definitions – Statistics
  • Data: The facts or figures (observation / information collected) which are numerical or otherwise, collected with a definite purpose, are called data.
  • Primary data: The data collected by the investigator himself for a definite plan or purpose, is known as primary data.
  • Secondary data: The data which are not collected directly but obtained from some other sources (published or unpublished), is known as secondary data.
  • Frequency Distribution: The number of entries of the data having their values lying in a class is defined as the frequency of the class. The table in which the corresponding frequency are written against each class, is called the frequency distribution of the given data.
  • Class Interval: Class intervals are the groups in which all the observations are divided. Each class is bounded by two figures or numbers which are called class limits. The difference between the upper limit and the lower of a class is called class size.
  • Frequency Polygon: A frequency polygon is the polygon obtained by joining the mid-points of upper horizontal sides of all the rectangle in the histogram. It can also be drawn independently without drawing histogram. For this we find class mark of each class interval.
  • Mean: The mean of a number of observations is the sum of the values of all the observations divided by the total number of observations.
  • Median: Median is that value of the given observation, which divides it into exactly two parts.
    Mode: Mode is that value of the given data, which occurs most frequently.
