Research concepts: Quantifying scatter

In a previous post we used binary data to demonstrate sampling error and calculate 95% confidence intervals (CI). Now, suppose that data can take many values; for example, normal body temperature has many values and varies continuously over a physiological range. How can we measure this variability in body temperature? For continuous data, variability can be quantified as the standard

R: Analysing small datasets – Part 2

In the previous post we plotted repeated measures data from 10 subjects under 2 conditions. There are different ways to analyse small datasets. We could apply parametric methods to analyse the data values, such as describing the data with means and standard deviations, and calculating a paired difference. Or, we could also apply non-parametric methods by analysing data values based
