Session 2 Central tendency means most scores(68%) in a normally distributed set of data tend to cluster in the The Population Formulas for Variability. 3. Mean, x is the average from sample and mean, P is the average from population. 1 This measure is used to provide a single value, which represents the “centre” of the sample data points/ distribution. Measures of central tendency – mean median, mode, geometric mean, harmonic mean for raw data Arithmetic mean or mean Arithmetic mean or simply the mean of a variable is defined as the sum of the observations divided by the number of observations. 2. What measure of central tendency is calculated by adding all the values and dividing the sum by the number of values? It approaches the mean calculated from the raw data as the number of intervals … Mean - is the most commonly used measure of central tendency. Md= 7 + 8 2 = 7.5 Hence, the median of the set of scores is 7.5 The next activity is another measure of central tendency. The mean is 2 .

It is a quick approximation of the average. The main objectives of Measure of Central Tendency are 1) To condense data in a single value. The measures of central tendency presented here for ungrouped data are the mode, the me-dian, the mean, and quartiles. Introduction A When actual data is unavailable or of an unmanageable volume, it may be necessary to determine parameters and statistics using a frequency distribution. Measures of central tendency show us how the data tends to cluster around a particular value, or “centralize.” They provide descriptive values that we often think of as a typical value of the data. This quantity is termed a measure of central tendency. Measures of Central Tendency A measure of central tendency is a single value that attempts to describe a set of data by identifying the central position within that set of data. Choosing the best measure of central tendency depends on the type of data … Measures of Central Tendency- Meaning. The most commonly used measures are mean, medium and mode.
