Which of the following is not a method of average calculation ?

The correct answer is - Correlation

Key Points

• Correlation
  • Correlation is not a method of average calculation. It is a statistical tool used to measure the strength and direction of the relationship between two variables.
  • Unlike averages such as Mean, Median, and Mode, which summarize data points into a central value, Correlation focuses on the association between two sets of data.
  • For example, the correlation coefficient (denoted as r) ranges between -1 and +1, indicating negative, no, or positive relationships between variables.

Additional Information

• Methods of Average Calculation
  • Mean: It is the arithmetic average of a set of numbers, calculated by dividing the sum of all values by the total number of values.
  • Median: It is the middle value of a dataset when arranged in ascending or descending order. For even-numbered datasets, the median is the average of the two middle values.
  • Mode: It is the value that appears most frequently in a dataset. If no value repeats, there is no mode.
• Key Differences Between Averages and Correlation
  • Averages summarize a dataset into a single representative value.
  • Correlation measures the relationship between two datasets but does not summarize them into a central value.
  • Correlation is often used in regression analysis, while averages are used for descriptive statistics.
