... Median and mean are both measures of center, but sometime we must make the selection of which to use to describe the distribution. To use Mean or Median depend of the SHAPE of the Distribution: Symmetric and bell-shape: mean and median will be close Distribution has outliers or is strongly ske ...

3.2 Measures of Spread
... 3.2 Measures of Spread In some data sets the observations are close together, while in others they are more spread out. In addition to measures of the center, it's often important to measure the spread of the data. One measurement of variation that is easy to calculate is the range. Range = (Largest ...

Part IV - The University of Edinburgh
... Let’s demonstrate the CLT using a simulation. We assume that Xi ∼ i.i.d. uniform(160, 180). That is, we assume that the Xi ’s are uniformly distributed within the interval [160, 180]. We proceed as follows: 1. We draw n = 50 observations (x1 , . . . , x50 ) from our “population” (in this case: from ...

... (a) In which region is income the most evenly spread? Solution: The sample standard deviation is given as our measure of spread in the data. Because the standard deviation is scale dependent, we need to adjust this measure of dispersion by its mean. Hence we calculate the coefficient of variation (C ...

... A hypothesis test is a procedure for testing a claim (or hypothesis) about a parameter of a population. First, you identify the null hypothesis (H0), which is the original claim held by nature, or previous studies. Second, you identify the alternative hypothesis (H1) that differs from the H0. Next, ...
