Applying Probabilities
Potentially, you can apply the same predicted probability to three groups:
-
All Adults. If you see a way for your selected values to apply to
all 112m adults,
you can regard those values as targets to hit to increase (or decrease)
the 58% (.58) and 65m numbers.
To ensure they apply, select hold constant for the Respondent Race socio-demographic variable.
-
The Target.
If you select socio-demographic values that cannot apply physically to all adults (e.g., everyone cannot
be Black or white), the target group will re-size in accord with Census population estimates.
So if you choose Respondent Race ("Black"), the results
will apply only to the 10.6m (112*.095) Black adults residing in the US in November 1963.
-
Specific Individuals. If the values you choose are your own, or those of someone you had in mind, the resulting estimate will be your, or their, predicted probability.
