The “Normal” Shape » Biostatistics » College of Public

A normal probability plot is a scatterplot of the data vs. the expected quantiles. the plot is shown below. If the data indeed come from a normal distribution, then the scatterplot should deviate in a random fashion from the reference line. Note that the 45 degree line serves as a convenient reference line for detecting a systematic departure from normality.

Examining the distribution of your data using histograms

20/04/2012 · If the data are normally distributed, the result would be a straight diagonal line . A Q-Q plot is very similar to the P-P plot except that it plots the quantiles (values that split a data set into equal portions) of the data set instead of every individual score in the data. Moreover, the Q-Q plots are easier to interpret in case of large sample sizes
