0
It is a variable which usually the values 0 and 1 depending on the presence and absence of a particular factor in a set of trails. Similarly, the gender of a person could be coded as 0 (= Male) and 1 (= Female) - or the other way around. The actual coding does not matter but it allows for comparisons between the two sub-sets of the population.

How do you interpret coefficient of dummy variable?
To interpret the coefficient of a dummy variable is to follow all of the steps of the equation that is being used as if the dummy variable was a real one.
What is a dummy variable in Operations research?
There are various forms. In linear programming, a dummy variable may be used to convert an inequality into an equation. For example x < 10 can be written as x + u = 10 where u > 0. In this case, it is also called a slack variable. Dummy variables are used in regression to indicate the presence or absence of a factor, or for binary variables. For example, male/female could be coded numerically as 0/1 where, because the question is binary, the exact coding does not matter.
How do you find the z score of 12.5?
To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.To find the Z score from the random variable you need the mean and variance of the rv.
Is the expected value of a discrete random variable equal to the mean of the random variable?
yes?
What is the probability of an observation being above the mean?
For a continuous variable it is 0.5 but for a discrete variable the answer depends on the probability of the variable taking the mean value. It is half of the rest of the probability. If the discrete variable X has mean m and Prob(X = m) is p then Prob(X > m) = (1 - p)/2.

Is a dummy variable equal to y?
It can be.
Difference between dummy and categorical variable?
A dummy variable assumes a value of either 0 or 1. A categorical variable assumes one of a usually small number of values. For example, a categorical variable might assume the values 'F' or 'M' for female or male.
How to change superiority to equality?
Add a negative dummy variable to the side that was superior, or a positive dummy variable to the side that was inferior. For example, X > 5 could be replaced by X-a = 5 or X = 5+b where a and b are positive.

What are dummies variables?
A dummy variable is a variable that takes on the values 1 and 0; 1 means something is true. These are used in statistical analyses.
What does void mean in C programming?
It's a dummy variable for functions. It's usually used when there's no actual value returned from the function, but you want the operations within the function to be caused to occur.
