Correções

1) Some people want to buy the products whereas other people do not want to.

2) ...in order to meet the expectations of more consumers.

3) The anthropologic approach is much more valuable to obtain soft data than the “external” approach is.

4) The number of sales you are likely to do.

5) This is true only if when the product was brought to the market for the first time, no market research with hard data had been made before.

6) They focused on fun and human relations rather than well-being.

7) People are not expected to act rationally but as human with subjective reasons.

8) The subjective reasons are, at least, as important as rational reasons while making a purchasing decision.

9) Maybe the product is not used in the way the sellers expect it to be used, maybe the product has not the social status the seller think it has.

10) The soft data are very useful for the market researches dealing with products which do not exist at all in the market you study because you do not know how the consumers substitute the product, how they will react to the new product… .

11) (The hard data are...) OR (Hard data are...) . Thank you
