However, in statistics, you’ll come across dozens of types of variables. In most cases, the word still means that you’re dealing with something that’s unknown, but—unlike in algebra—that unknown isn’t always a number. Some variable types are used more than others. For example, you...

Both descriptive and inferential statistics are types of statistical analysis used to describe and analyze data. Here are the main differences between them:Definition Descriptive statistics use measures like mean, median, mode, standard deviation, variance, and range to summarize and describe a data ...
So, you understand the different types of data, what you can learn from them, and how to graph them—how else can you use this knowledge? In statistics, the type of variable greatly determines which kinds of analyses you can perform. Read the following posts to learn how to choose a sta...
There are several types of bias in statistics, and avoiding and understanding these statistical biases can help you better interpret data. Here are some of the different types of statistical biases you may encounter. Confirmation bias Confirmation bias is an error that involves allowing a ...
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...
Master of Science (MS, MSc) A Master of Science (MS, MSc) is usually awarded in disciplines categorised as the sciences, such as biology, chemistry, engineering, health and statistics. Certain fields such as economics and the social sciences can fall under both arts and sciences, with the ...
Descriptive statistics often stands at the beginning of data analysis and is often combined with other methods. Data from the past are analyzed in order to draw conclusions. Before one can test one's actualhypotheses, one should check whether the variable of the sample is normally distributed, ...
One way to reduce the likelihood of sampling error is to use a larger sample size. The Monthly Employment Situation report, compiled each month by the U.S.Bureau of Labor Statistics, is calculated from a survey of 119,000 businesses and government agencies. Due to the enormous sample size,...
