are helpful in understanding changes in market-implied uncertainty after an FOMC meeting.
To see how central tendency
might be used for interpreting a single test, consider a 50-item final examination called Test x for which the mean, median, and mode turned out to be 24.
Statistical hypothesis: the null hypothesis is that the central tendency
of EB ss is the same for students who have repeated and for those who have not repeated school grades [H0: E(rep) = E(no rep)]; the alternative hypothesis is that the central tendency
of the scores is different [H1: E(rep) 4 E(no rep)]According to the Mann-Whitney test it was not possible to reject the null hypothesis, nor for the total test (U = 87855, Z = 1.

Standard CPI is the traditional measure for inflation, but a few extreme outliers (such as the price of fuel) can throw off the average; thus the median is a more robust statistic to estimate the central tendency

Descriptive statistics such as frequency distributions and measures of central tendency
were used to identify patterns in the data relating to rubric usage and corresponding assessment outcomes (Johnson & Christensen 2004).
