Ho for chi square test goodness of fit
|
states the PROPORTION of cases in each category of a population of qualitative data
|
|
|
goodness of fit problem
|
asks whether the relative frequencies observed in the categories of a sample frequency distribution are in agreement with the relative frequencies expected to be true in the population
|
|
|
chi square statistic
|
provides a measure of the difference between observed and expected frequencies
|
|
|
X2 cannot be
|
negative because all the differences are squared; both positive and negative differences make a positive contribution to the value of X2
|
|
|
The null hypothesis is that in the
|
POPULATION, the proportional frequency of cases in each category equals a specified value. The proportions hypothesized are derived from a research question of interest to the researcher
|
|
|
Ho for chi square test of contingency table
|
states that in the population, there is no relationship between the two variables; in practice, a test about proportions
be able to fill out a contingency table!! |
