PRACTICE QUESTIONS FOR MEASURES OF CENTRAL TENDENCY
Practice question 9 6(SYMMETRICAL DISTRIBUTION):- (a) In a perfectly symmetrical frequency distribution the mean of the data is 88 Find median and mode |
The data vary about a measure of central tendency and the measures of deviation are called measure of variation or dispersion.
The data in frequency distribution may fall into symmtrical or asymmetrical patterns.
The measures of the directions and degree of asymmetry are called measure of skewness.
What are the three most commonly used measures of dispersion?
Thus to describe data, one needs to know the extent of variability.
This is given by the measures of dispersion.
Range, interquartile range, and standard deviation are the three commonly used measures of dispersion.
Why are measures of dispersion used as well as measures of central tendency?
While measures of central tendency are used to estimate "normal" values of a dataset, measures of dispersion are important for describing the spread of the data, or its variation around a central value.
How do you measure central tendency and dispersion?
Measures that indicate the approximate center of a distribution are called measures of central tendency.
Measures that describe the spread of the data are measures of dispersion.
These measures include the mean, median, mode, range, upper and lower quartiles, variance, and standard deviation.
