Summary and Conclusion
In order to make a survey valid and reliable researchers must consider all factors involved. Survey's must include subjects from varying social and economic backgrounds. This survey could have been made more concise if random sampling (is a method in which subjects are randomly selected from various areas) was used (Teevan, 1995:162). This would ensure that there would not be any biases involved when choosing subjects. The researcher when initializing this survey overlooked the possibility of double-income households and therefore, documented the fathers as the only means of income in a family. As a result, the research is only accurate in measuring single income families, providing that the wealthier fathers made more on average compared to the poorer ones. In conclusion, straight correlation study methods used in survey research like 'Horatio Alger lives' will lack components of validity and reliability due to these facts previously mentioned.
