Changing into the Solve aplet we can enter a
formula which will allow us to calculate values
from the Chi
2
distribution using the UTPC
function.
With a 3 x 2 contingency table the number of
degrees of freedom are 2. To find the critical
2
0.05
value, we enter values of 2 for D (the
degrees of freedom) and 0.05 (the probability)
and then move the highlight to V (the value)
and press . As it turns out, the required
critical value is 5.99 and so we would accept the null hypothesis and
conclude no relationship.
