The Cumquat Café began advertising on our local radio station this year and was delighted to see its business increase by 10 percent over last year’s totals. Their success shows you how you can use radio advertising to make your business more profitable.”The argument claims that you can use radio advertising to make your business more profitable and provides an evidence that the Cumquat Café began advertising on local radio station this year and was delighted to see its business increase by 10 percent over last year’s totals. Stated in this way, the argument failed to mention several key factors, based on which it can be evaluated. The conclusion of the argument is based on assumptions, for which no clear evidence is provided. Hence, it is weak and has several flaws.
Firstly, the argument claims that the sale of the café increase by 10 percent over last year’s totals and it mentioned nothing about the sales of past several years. The data of sale of past 5-6 years must be provided to clearly identify whether the sales of café increased actually by radio advertising or increase in sales is a general trend of past several years. By clearly examining the relevant data , it can be concluded that radio advertising actually increased the sales.
Secondly, the argument assumes that it is the solely radio advertisement which increased the sales of café. It does not provided any data about the changes which café implemented during last year. And possibly, some other change not the radio advertisement itself was responsible for this increase in sale.
For example: last year the café introduced a additional item for sale. As a result, the sales of the café increased by 10 percent.
Additionally, the argument failed to mention several factors which can directly negotiates the conclusion. May be, the sales of café increased not by radio advertisement but by opening of a big mall or industry near the café. And increased population near the café resulted in increase of sales. Clearly, argument is weak without relevant data. And, conclusion of the argument has no legs to stand on.
In conclusion, the argument is flawed for the above mentioned reasons, and therefore, is unconvincing. It can be strengthened by adding more relevant data. In order to access the merits of some situation/decision , it is important to have full knowledge of contributing factors. Without all these, the argument is weak and thus, open to debate.
