The usual measures of variability cannot.
Yes. The greater the range, the greater the variability.
minimizes the within-class variability while at the same time maximizing the between-class variability.
Why are measures of variability essential to inferential statistics?
The range, inter-quartile range (IQR), mean absolute deviation [from the mean], variance and standard deviation are some of the many measures of variability.
Variability is an indicationof how widely spread or closely clustered the data valuesnare. Range, minimum and maximum values, and clusters in the distribution give some indication of variability.
Genetic variability refers to the differences in DNA sequences among individuals in a population. This variability is essential for evolution as it allows for adaptation to changing environments and the development of diversity within species. Genetic variability can arise from mutations, genetic recombination, and gene flow.
discuss the importance of measuring variability for managerial decision making
Variability in a population affects the required sample size for a study. Higher variability typically necessitates a larger sample size to achieve a desired level of precision and confidence in the results. Conversely, lower variability allows for a smaller sample to adequately represent the population. Thus, understanding the extent of variability is crucial for determining an appropriate sample size to ensure reliable and valid conclusions.
