Statistics II Central tendency and spread of data BJA
Measures of Central Tendency. Three of the many ways to measure central tendency are: 1. Mean: the average of the data : 2. Median: the middle value of the ordered data: 3. Mode: the value that occurs most often in the data: In most research experimental situations, examination of all members of a population is not typically conducted due to the cost and time required. Instead, we typically... There are three commonly used measures of central tendency – the mode, median, and mean of a distribution. The mode is the most common value or values in a distribution. [1] The median is the middle value of a distribution. [2]

“Measures of central tendency” are used because they represent centralized or middle values of the data. These measures of central tendency are called the “mean,” “median,” and “mode.” 3. The “mean” is a number that represents an “average” of a set of data. It is found by adding the elements in the set and then dividing that sum by the number of elements in the set

  • Measures of Central Tendency * Mean, Median, and Mode * Locates the distribution by various points * Use this when you want to show how an average or most commonly indicated response. 3. Measures of Dispersion or Variation * Range, Variance, Standard Deviation * Identifies the spread of scores by stating intervals * Range = High/Low points * Variance or Standard Deviation = difference between
  • Different types of data need different measures of central tendency to describe the distribution of data. For highly skewed data, none of these may be sufficient, and we may need to go for other specialized measures or simply report them all in a table.
