In this lesson, only numbers will be considered. Here are some examples of inequalities: Greater than: {eq}x>3 {/eq}. Greater than or equal to: {eq}x \geq 5 {/eq}. Less than: {eq}x < 8 {/eq}. Less than or equal to: {eq}x \leq -4 {/eq}....

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...
Similarly, theprediction intervaltells you where a value will fall in the future, given enough samples, a certain percentage of the time. A 95% prediction interval of 100 to 110 hours for the mean life of a battery tells you thatfuture batteries producedwill fall into that range 95% of th...

There are other ways of classifying variables that are common in statistics. One is qualitative vs. quantitative. Qualitative variables are descriptive/categorical. Many statistics, such as mean and standard deviation, do not make sense to compute with qualitative variables. Quantitative variables have ...
As you can see, descriptive statistics help you to gain an overall picture of your nominal dataset. Through your distribution tables, you can already glean insights as to which modes of transport people prefer. Visualizing nominal data Data visualizationis all about presenting your data in a visua...
Finally, we illustrate these confidence intervals with two real data examples, and in the second example some existing intervals do not exist.doi:10.1080/02664763.2016.1247793Yan, LiangBeijing Inst TechnolWang, RuiBeijing Inst TechnolXu, Xingzhong...
Answer to: What is the difference between a Z and t confident interval in statistics? When would you use one over the other? By signing up, you'll...
Sometimes in statistics, it is helpful to see worked out examples of problems. These examples can help us in figuring out similar problems. In this article, we will walk through the process of conducting inferential statistics for a result concerning two population means. Not only will we see ...
