Review Exercise for Section 46 Correct errors.

In the 1970s, market researchers discovered that most young children were unable to distinguish TV programs and product advertisements they saw. For this discovery, in 1978 an attempt was made to impose legal restrictions on TV commercials targeting children, but advertisers opposed it. Since then, the child marketing industry has steadily grown. Between 1978 and 1998, the amount of direct expenditure by children between the ages of 4 and 12 rose from less than $ 3 billion per year to nearly $ 25 billion, but that has not ended yet. Researchers believe that children of this age will convince families to add $ 200 billion annually. For example, a boy convinced a mother to purchase more expensive computers than originally purchased. Marketers can easily decide to target this young market. Their job is to be convinced and target the most money-consuming consumers.

However, there is no other group to help marketers find the best way to target young people. Many child psychologists are now required to participate in market research firms to provide information on how to reach children more effectively. Several members of the American Psychological Association trained advertisers targeting APA children by working on their organization in 2002, but APA has not taken action yet. Most psychologists think that marketers and their consultants are very free to attract children who can not make informed decisions about products, but this situation seems unchanged.

The informal evaluation of the popular IT magazine PC Pro in the 2007 article "The Secret of Wikipedia" introduces ten mistakes as "mistakenly subtle bleeding" (researchers later I modified them to test Wikipedia.

In the software maintenance organization, an error occurred with 55% single row maintenance change before introducing code review. After introducing the comment, only 2% change was wrong. After reviewing all the changes, 95% was the correct answer for the first time since the review began. Before introducing comments, less than 20% is correct for the first time. Of the eleven program groups developed by the same group, the first five programs were developed without comments. The remaining six were developed by comments. After all programs have been released to production, the first five programs have an average of five errors per 100 lines of code. The average value of the six tested was only 0.82 errors per 100 errors. Reduce review errors by 80% or more
