C784 Applied Healthcare Statistics
Module 4: Key Concepts, Practice
Problems & Exam Preparation
Outlier An observation point that is significantly distant from
the other observations in the dataset
Mode The most frequent value in a dataset
Statistics The science that deals with the interpretation of
numerical facts or data through theories of
probability. Also, the
numerical facts or data themselves.
Standard Deviation (SD) The measure on average of how far the data points
are from the mean
Mean Average, calculated by adding a series of elements
in a data sat together and dividing by the total
number in a series. (Symmetric distribution)
Box plots (box-and-whisker plots) A graphical rendering of the range and the first and
third
quartile of a data set with the data set's median in
between. Useful in illustrating the distribution shape
of a date set.
Symmetry The quality of the data having the same shape on
both sides of the mean
Interquartile Range (IQR) The difference, value, between the bottom and the top
25% of the sample or population.
Range The difference between the maximum and minimum
values
maximum The largest value in a set
Measure of central tendency A summary measure that is used to describe an entire
set of data with one value that represents the middle
or center of the data set's distribution. There are
three main measures: mean, median, or mode.
normal distribution (bell curve) A common type of distribution of data points that
forms a bell shaped, symmetrical curve around the
mean
