At Scientifically Sound, we have shown how to verify whether data are Normally distributed, and discussed whether it matters that data are Normally distributed. Let’s take a step back and consider what a Normal distribution is. A Normal distribution is a bell-shaped curve observed when the number of data points that occur in a population (y-axis) is plotted against the

In our previous post we learned about Python virtual environments and how conda makes it easy for us as scientists to use virtual environments and access hundreds of useful packages. Despite the number of packages directly available through conda, not all packages can be downloaded this way. In this post we will learn how to add such packages to our

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
