You need to know which types of variables you are working with in order to choose appropriate statistical tests and interpret the results of your study. You can usually identify the type of variable by asking two questions: What type of data does the variable contain? What part of the experi...
Outside of statistical research,reliabilityandvalidityare used interchangeably. For research and testing, there are subtle differences.Reliabilityimplies consistency: if you take theACTfive times, you should get roughly the same results every time. A test isvalidif it measures what it’s supposed to...
The simple random sampling process entails six steps, each performed in sequential order. Step 1: Define the Population The starting point of statistical analysis is to determine the population base. This is the group about which you wish to learn more, confirm ahypothesis, or determine a statis...
Publication bias is related todata dredging(also calledp-hacking), where statistical tests on a set of data are run until something statistically significant happens. As academic journals tend to prefer publishing statistically significant results, this can pressure researchers to only submit statistically...

Chi-square is a statistical test used to examine the differences between categorical variables from a random sample in order to judge the goodness of fit between expected and observed results. Who Uses Chi-Square Analysis? Since chi-square applies to categorical variables, it is most used by res...
