Document Summary

Itis a single value that is used to identify the center of the data. Itis taught as the typical value in the set ofscores. It tends to lie within the center if it is arrangedfrom lowest to highest and vice versa. \ Used when the data are interval or in ratio level of measurement. * used when the frequency distribution is regular, symmetrical or normal. * used to compute other measures such as standard deviation, coefficient of variation, * when it is desired to give each score equal weight in determining the central tendency. when it is desired to find the measure of central tendency which has the highest reliability. * when it is desired to compute the standard deviation and the coefficient of correlation later on. Steps in solving the mean value using raw scores: get the sum of all the scores in the distribution. 2: substitute to the given formula and solve the mean value.

i just need example please

Q1: Discuss why mean is the most widely used measure of centraltendency in the health science research? Justify your answers withevidence.

Answer: In medical research the measure of central tendency iseverywhere. But by far the most important and frequent use aremean, the median, and the mode which is most frequent value in thedistribution. Mean is most commonly used measure of centraltendency with varied types i.e. arithmetic, weighted, geometric,and harmonic mean.

The mean uses every value in the data and hence is a goodrepresentative of the data. It is closely related to standarddeviation, the most common measure of dispersion.

Investment analysts are using different measurements such as standard deviation, Skewness, value at risk (VaR), Beta (systematic risk), Sharp and Treynor measures to quantify risk and the effect on their target portfolio. You are required to write an essay (with word limit 500) on the topic “The importance of the above measurements to quantify and managing risk”.
