Document Summary
H1= there is a correlation between the age of the respondent and the length of the traic stop. When the age of the respondent is increasing, the length of the traic stop is also increasing. Before running the statistical analysis make sure to check out whether the relationship is linear. The line is straight, so it is linear. It tells us, there is a negative linear relationship between them. Now it is time to look at whether it is statistically signiicant. b) 83: the pierson correlation is negative and it is -. 113. It is not signiicantly correlated because it is bigger than the p value which is . 05. As a result, we retain the null and reject the alternate. There are 4 variables in the spss datafile. H1= there is a correlation between the number of face- to face police contacts and the length of traic stop. b) Correlation is significant at the 0. 01 level (2-tailed).
