A continuous variable is any variable that can be any value in a certain range. The other possible type of variable is called a discrete variable. This type of variable can only be certain specific values. For example, when flipping a coin, it can land either on heads or tails. If you've been shopping for a new car recently, you've undoubtedly found that large numbers of late-model vehicles are equipped with a continuously variable automatic transmission (CVT). It's a Continuous variables are numeric variables that have an infinite number of values between any two values.

3 Besides aspects of suitability of the variable as an indicator for your concept and missing values and other measurement problems, the following statistical aspects  of continuous variables are body mass, height, blood pressure and cholesterol. A discrete quantitative variable is one that can only take specific numeric values (  19 Dec 2018 Continuous variables are variables that can take on any value within a range. Continuous variables are also considered metric or quantitative  September, 1954 Correlation Between a Discrete and a Continuous Variable. Point-Biserial Correlation. Robert F. Tate.

For example, the time you have to wait for a bus could be considered a random variable with values in the interval $$[0, \infty)$$.

Before we look at the Pearson correlations, we should look at the scatterplots of our variables to get an idea of what to expect. Discover using the -margins- feature to compute predictions from a linear regression model with a continuous covariate. The second method is more common; take the sum or mean of two or more ordinal variables to create an approximately continuous variable. The opposite of a variable is a constant. A constant is a quantity that doesn’t change within a specific context. In scientific experiments, variables are used as a way to group the data together. A continuous variable is any variable that can be any value in a certain range. The other possible type of variable is called a discrete variable.

Solution. First, note that \textrm{Var}(Y)=\textrm{Var}\left(\frac{2}{X}+3\right)=4\textrm{Var}\left(\frac{1}{X}\right), \hspace{15pt} \textrm{using Equation 4.4 I have a continuous variable, which can take any value between 0 and some large, though not infinite, number.

This level of detail is paramount for scientists, doctors and manufacturers, just to name a few.
