Is a survey a statistical tool?
Before you can decide which statistical tool to use, you must first understand the data being collected. Surveys are often in questionnaire form, with answers varying from multiple choice to open-ended. There are also two major types of statistics: descriptive and inferential.

How to analyze survey stats?
How to Analyze Survey Results Categorical Data. Calculate the total number of responses and then divide the number in each category by the total. Ordinal Data.

What is an example of a statistical test?
A classic use of a statistical test occurs in process control studies. For example, suppose that we are interested in ensuring that photomasks in a production process have mean linewidths of 500 micrometers. The null hypothesis, in this case, is that the mean linewidth is 500 micrometers.
