Front 1

Chi-squared statistic (X2): is a statistic that .......... the difference between the .......... data and what would be ................ if the two variables were independent

Back 1

estimates, observed, expected

Front 2

Chi-sq = the sum of (...-E)sq/....

Back 2

O, E

Front 3

The degrees of freedom (df) = (r-1)(c-1). Where r is the # of ...... and c is the number of..............

Back 3

rows, columns

Front 4

Adjusted standardised residuals: are residual that are standardised so as to be equivalent to a ..-score in a .................. distribution.

Back 4

z, normal

Front 5

In a normal distribution a Z-score above...... is large

Back 5

2

Front 6

If the chi-sq statistic is large enough there is evidence that the two variables are NOT .................. but are ...................

Back 6

independent, associated

Front 7

we can draw conclusions about associations between c........... variables, using ....... hypothesis significance testing

Back 7

categorical, null

Front 8

If X2 is large enough here is evidence to reject the?

Back 8

null hypothesis

Front 9

if the probability of X2 is less than 0.....reject the null hypothesis. if you reject the nh you have evidence for an ................. btwn the two variables

Back 9

0.05, association

Front 10

adjusted standardised residuals permit one to draw inferences about the ............... of any .............. association

Back 10

direction, significant
