How To Interpret Standard Deviation (3 Key Concepts To Know)
It is one thing to calculate a standard deviation from a data set. However, it is another to interpret it and find out what it is telling you about a data set. So, how do you interpret...
In math, definitions are the first thing we learn to build our knowledge. The concepts of equations and expressions are important, but how are they connected? So, what is the difference...
Standard Deviation vs Standard Error (3 Key Concepts To Know)
In statistics, we describe data sets using both standard deviation and standard error of the mean (also called standard error). Although these two terms sound similar, there are some key...
In calculus, derivatives and integrals are two different concepts – but they are related in an important way. Both tell us something about a function and its behavior, but it helps to know...
Domain and range are two important concepts when we talk about functions. Depending on domain restrictions, the graph of a function will look different (and may even have an inverse). So,...
When we talk about functions in math, we want to know what set of output values are valid and possible (known as the range or image of the function). Knowing the range of a function also helps...
