Consumer Research Inc. The results from the following graph shows that out of sample of 50 respondents in Dubai and Abu Dhabi majority of the respondents had their family size of 2 people i.e. majority of them were couples. Further, a fair percentage of respondents had a family size of 3 or 4 people but very few had that for 5, 6 and 7.

On the other hand, the income size of the respondents is well normally distributed from AED 20000 to AED 60000 but majority of the respondents had their income in the range of AED 21000 to AED 30000 and also greater than AED 61000 i.e. a significant amount of variation exist in their incomes.

The mean income of the respondents [n = 50] is found to be AED 43.48 (000's) which shows significant variation against the above histograms but as discussed, it is due to high variations in income levels i.e. few quite a few had their income in the range of AED 21 - 30 (0000's) and quite a few had greater than AED 61 (000's). Similarly, the amount charged in credit cards has its mean value AED 3964.06 which is almost 9.11% of their average income. The median and mode in amount charged in credit cards is significantly close to that of the mean which shows less variation in the credit card fees. But the modal values of income are significantly varying from that of the mean which shows higher variations in income.
