Document Summary
Will think there"s a relationship between x and y if the p-value is lower than this level. Want small p-values (typically p < 0. 05) Means that there is a less than 5% likelihood that the results are due to chance. Null hypothesis: no relationship between iv and dv. Ex. there is no relationship between education and information level. Alternative hypothesis: there is a relationship between the iv and dv. For one variable changing, the other variable is also changing. Ex. as education level increases, political information level increases. If we find no support for the alternative hypothesis. If we do find support for the alternative hypothesis. Don"t say we accept the alternative hypothesis . Compare test statistic to what we"d expect if the null hypothesis were true. Aka. calculate one #, calculate another #, compare #"s. Females are more inclined to vote for obama. Use bolded values (rows and columns #) to calculate degrees of freedom.
