3. What does Somers d value of -0.70 specifically tell you about the nature of the relationship between the two variables in a crosstab table?
4. Calculate the degrees of freedom associated with a 5 by 4 crosstab table. Show the solution.

3)
Somers d = -0.7 means that there was an inverse relationship between two variables.
Somers’d is a non-parametric measure of the strength and direction of association that exists between an ordinal dependent variable and an ordinal independent variable.
4) Given that
Number of rows = 5
Number of columns = 4
Degrees of freedom = (rows-1)(columns-1) = (5-1)(4-1) = 12
Degrees of freedom = 12

need help answering question two.
what does your observation tell you about the silver nitrate
test?
in the directions we have "the silver nitrate chemical
test makes use of strong affinity that Ag(I) cations have for
bromine and other halogens, resulting in precipitation of insoluble
AgBr from your rcn if the sample contains bromine.
but that doesnt make since completely to me.
help please!
