WebApr 5, 2024 · All statistical techniques fall into two broad categories: descriptive statistics (which summarize a dataset’s features) and inferential statistics (which help us make predictions based on those data). Determining if you’re working with nominal, ordinal, interval, or ratio data helps narrow down which technique to use. To get an overview of your data, you can first gather the following descriptive statistics: 1. the frequency distributionin numbers or percentages, 2. the mode, median, or mean to find the central tendency, 3. the range, standard deviation and variance to indicate the variability.
