Question
A study of 10 000 loans examines the association between homeownership (rent, mortgage, or own) and application type (individual, or joint). A test of independence
A study of 10 000 loans examines the association between homeownership (rent, mortgage, or own) and application type (individual, or joint).
A test of independence is conducted using =0.05, where standardized residuals are considered significant if they are more extreme than +/-2.
The Excel sheet for this question shows the observed frequencies and the standardized residuals.
What do the standardized residuals tell us about the relationship between homeownership and application type?
Fill in the blanks for the sentences below, ONLY interpreting standardized residuals that are statistically significant. Remember that expected values refer to what is expected assuming that the null hypothesis is true.
1. Loan applicants who rent their home are _______ (Less likely to apply/morelikely to apply/have similar frequency of individual application)
2. Loan applicants who have a mortgage on their home ______(Less likely to apply/morelikely to apply/have similar frequency of individual application)
3. Loan applicants who own their home_______(Less likely to apply/morelikely to apply/have similar frequency of individual application)
OBSERVED FREQUENCIES | Homeownership | ||
Application type | Rent | Mortgage | Own |
Individual | 3496 | 3839 | 1170 |
Joint | 362 | 950 | 183 |
STANDARDIZED RESIDUALS | Homeownership | ||
Application type | Rent | Mortgage | Own |
Individual | 3.749 | -3.667 | 0.568 |
Joint | -8.943 | 8.747 | -1.355 |
