The value of the categorical variable that is not represented explicitly by a dummy variable is called the reference group. In this example, the reference group consists of Independent voters. In analysis, each dummy variable is compared with the reference group. In this example, a positive regression coefficient means that income is higher for the dummy variable political affiliation than for the reference group; a negative article source coefficient means that income is lower. If the regression coefficient is statistically significant, the income discrepancy with the reference group is also statistically significant.

Test Your Understanding In this section, we work through a simple example to illustrate the use of dummy variables in regression analysis.

The example begins with two independent variables - one quantitative and one categorical. Notice that what does a dummy run mean the categorical variable is expressed in dummy form, the analysis proceeds in routine fashion. The dummy variable is treated just like any other quantitative variable. For instance, if you take an average of a 0,1 variable, the result is the proportion of 1s in the distribution. To illustrate dummy variables, consider the simple regression model for a posttest-only two-group randomized experiment. This model is essentially the same as conducting a t-test on the posttest means for two groups or conducting a one-way Analysis of Variance ANOVA. To see this, the first step is to compute what the equation would be for each of our two groups separately. Mad Dummy is infuriated that the protagonist took away the Dummy's future chance of becoming corporeal.

If the protagonist flees from the Dummy, Toriel acknowledges that fleeing can be a useful strategy, but points out that it was clearly unnecessary in this case, as the Dummy cannot attack, nor seek revenge. Mad Dummy is infuriated that the protagonist walked away from the Dummy, saying they were a "shy sort" and that the protagonist broke their little ethereal heart. If the protagonist checks, spares or misses attacks for 8 turns, it gets bored of the protagonist's aimless shenanigans and floats away. After this, Toriel stares in disbelief, then continues through the Ruins as if nothing happened.

Mad Dummy is disgusted by the protagonist's behavior and is glad the Dummy left like any self-respecting continue reading. Those in group 2 have 1 for d2 and 0 otherwise, and for group 3 d3 equals 1 with zero for the others. Observations in group 4 have all zeros on d1, d2 and d3. These three dummy variables contain all of the information needed to determine which observations are included in which group. If you are in group 1 then d1 is equal to 1 while d2 and d3 are zero. The group with all zeros is known as the reference group, which in our example is group 4. We will see exactly what this what does a dummy run mean after we look at the regression analysis results.
