Suppose the significance level is .02 for the relationship between political party preference and region. What does this mean?

What will be an ideal response?

Answer: It means that there are 2 chances out of 100 that the relationship between political party preference and region occurred just by chance in the sample and does not really exist in the population from which the sample was selected. Since we want this probability to be .05 or less in order to say that the relationship is statistically significant, this is a statistically significant relationship: we are deciding that there is a real relationship between these two variables in the population from which the sample was selected.
