Chapter 2 is about knowing your data. The better you know your data, the more likely you are to answer your research questions clearly. The specific type of data you have will dictate what statistics you can (and can’t) perform. Nominal data are categorical, such as binary task success ...

In statistics, there are four data measurement scales: nominal, ordinal, interval and ratio. These are simply ways to sub-categorize different types of data (here’s an overview of statistical data types) . This topic is usually discussed in the context of academic teaching and less often in...
We’ll briefly introduce the four different types of data, before defining what nominal data is and providing some examples. We’ll then look at how nominal data can be collected and analyzed. If you want to skip ahead to a specific section, just use the clickable menu. An introduction to...
anything about a population’s behavior (i.e. you’re just looking at data for a sample), you need to use thet-distributionto find theconfidence interval. That’s the vast majority of cases: you usually don’t know populationparameters, otherwise you wouldn’t be looking at statistics!
Ratio data has a defined zero point, whereas interval data lacks the absolute zero point. Interval data is measured so that each value is placed at an equal distance from one another in a clear order, while ratio data uses absolute zero as a reference point for measurement. Examples of ...
Clustered intervalcensored data contributes another complication that the failure times within the same cluster are not independent.Chapter 1 of this dissertation provides a detailed description of interval-censored data with several real data examples and reviews existing regression models and approaches ...
Here are some examples of inequalities: Greater than: x>3. Greater than or equal to: x≥5. Less than: x<8. Less than or equal to: x≤−4.Intervals on a Number Line Interval Notation Types of Intervals and Examples Lesson Summary Register to view this lesson Are you a student or ...
Ordinal scales are made up of ordinal data. Some examples of ordinal scales: High school class rankings: 1st, 2nd, 3rd etc. Social economic class: working, middle, upper. The Likert Scale: agree, strongly agree, disagree etc. TheLikert Scalegives another example of how you can’t ...
