C, and D.  Then press ! to

 3

T
Yate's corrected Chi-square is only

 3

T
calculated if one of the data entry

 3
 44
T
cells has a value of 5 or less.

 3
 45
T
If the Yate's correction is calculated

 3
 46
T
the value is reported in the results box

 3
 47
T
and the Yates value is used in determining

 3
 48
T
the significance of the Chi-square.

 3
 50
T
The critical value shown is for the level

 3
 51
T
of probability shown at the probability cell.

 3
 52
T
If probability is displayed as >.05 then

 3
 53
T
the critical value displayed is for the

 3
 54
T
.05 level. It is displayed for informational
