... a) Mean: the mean is the common arithmetic average. It is computed by dividing the sum of the values of the observations by the number of items observed. b)Median: the median is that item which lies exactly half-way between the lowest and highest value when the data is arranged in an ascending or de ...

... the true mean µx is replaced by the sample mean, x, then the denominator in the formula changes from n to n − 1. The value of the denominator is the number of degrees of freedom, ν, of the sample variance (or the sample standard deviation calculated from the variance). When sx2 (or sx ) is calculate ...

... What is the level of measurement (measure scale) of this variable? What is the best way to describe it in a “Patient Characteristics” table of a manuscript? The scores simply represent labels or classifications, which have no natural rank ordering. Thus, the level of measure is “nominal” or an “unor ...

... Sampling Distribution for Any Statistic Every statistic has a sampling distribution, but the appropriate distribution may not always be normal, or even approximately bell-shaped. Construct an approximate sampling distribution for a statistic by actually taking repeated samples of the same size from ...
