EXAMPLE: 51.1% of the 94 respondents are in the top management of their company. Hence there is approximately the same percentage of top and middle managers in the sample
Eiselrj: Now interpret the rest...
NOTE: These are cross-tabulations of a background variable with an opinion related question. For each pair of variables (a background and opinion variable), we wish to ascertain whether there is an association (dependency) between opinion and the background variable. Two hypoithesis tests can be used (see D&S), i.e. Fisher's Exact test or the Chi-squared test of independence depending on the siuze of the sample and the number of categories per variable EXAMPLE: 64.6% of top management believe that the meter accurately registers their company's electricity comsumption. In comparison 71.7% of middle managers believe the meter registers it accurately. Overall 68.1% of all respondents believe the mere reading is accurate.
NOTE: This is referred to as the significance or p-value
NOTE and EXAMPLE: This is the p-value (or significance value) related to the hypothesis test. If the p-value < 0.05, then it implies that there IS A DEPENDENCY (i.e. the null-hypothsis of independence (or no difference) is rejected). In other words there is a significant difference between middle managers and top managers in terms of their answers. If the p-value > 0.05, then top and middle managers do NOT differ significantly in terms of their opinion. In this case, the p-value>0.05 and hence there is not a significant difference between middle and top managers in terms of their opinion of billing accuracy

EXAMPLE: 51.1% of the 94 respondents are in the top management of their company. Hence there is approximately the same percentage of top and middle managers in the sample
Eiselrj: Now interpret the rest...
NOTE: These are cross-tabulations of a background variable with an opinion related question. For each pair of variables (a background and opinion variable), we wish to ascertain whether there is an association (dependency) between opinion and the background variable. Two hypoithesis tests can be used (see D&S), i.e. Fisher's Exact test or the Chi-squared test of independence depending on the siuze of the sample and the number of categories per variable EXAMPLE: 64.6% of top management believe that the meter accurately registers their company's electricity comsumption. In comparison 71.7% of middle managers believe the meter registers it accurately. Overall 68.1% of all respondents believe the mere reading is accurate.
NOTE: This is referred to as the significance or p-value
NOTE and EXAMPLE: This is the p-value (or significance value) related to the hypothesis test. If the p-value < 0.05, then it implies that there IS A DEPENDENCY (i.e. the null-hypothsis of independence (or no difference) is rejected). In other words there is a significant difference between middle managers and top managers in terms of their answers. If the p-value > 0.05, then top and middle managers do NOT differ significantly in terms of their opinion. In this case, the p-value>0.05 and hence there is not a significant difference between middle and top managers in terms of their opinion of billing accuracy
Eiselrj: Now interpret these after having read the relevant chapter of D&S
