Sample Size and Statistical Assumptions DQ

The discussion assignment provides a forum for discussing relevant topics for this week based on the course competencies covered. As in all assignments, cite your sources in your work and provide references for the citations in APA format. Make sure all references are cited in APA format. References should be current at least within the last 5 years.


Sample Size and Statistical Assumptions

Certain basic assumptions are necessary to allow for the statistical analysis of public health data. However, the validity of these assumptions can be affected by the sample size being analyzed.

The purpose of this assignment is to refresh your knowledge of the basic assumptions underlying the biostatistical analysis and to consider how these assumptions are affected by the sample size being analyzed.

Using the South University Online Library, the Internet, and your text readings, research the following statistical topics:

  • Statistical power
  • Central limit theorem (CLT)

On the basis of your research and understanding, respond to the following:

  • Find and state the definition of statistical power that you identify with.
  • State the definition of statistical power in your own words.
  • Compare and contrast type I and type II errors.
  • Explain how power is affected by sample size.
  • Find and state the definition of CLT that you identify with.
  • State the definition of CLT in your own words.
  • Summarize the basic assumptions underlying hypothesis testing and confidence interval methods.
  • Explain how these assumptions are affected by sample size.
  • Explain the relation of a sample size to the basic assumptions underlying biostatistical analysis.

You must proofread your paper. But do not strictly rely on your computer’s spell-checker and grammar-checker; failure to do so indicates a lack of effort on your part and you can expect your grade to suffer accordingly. Papers with numerous misspelled words and grammatical mistakes will be penalized. Read over your paper – in silence and then aloud – before handing it in and make corrections as necessary. Often it is advantageous to have a friend proofread your paper for obvious errors. Handwritten corrections are preferable to uncorrected mistakes.


Use a standard 10 to 12 point (10 to 12 characters per inch) typeface. Smaller or compressed type and papers with small margins or single-spacing are hard to read. It is better to let your essay run over the recommended number of pages than to try to compress it into fewer pages.


Likewise, large type, large margins, large indentations, triple-spacing, increased leading (space between lines), increased kerning (space between letters), and any other such attempts at “padding” to increase the length of a paper are unacceptable, wasteful of trees, and will not fool your professor.


The paper must be neatly formatted, double-spaced with a one-inch margin on the top, bottom, and sides of each page. When submitting hard copy, be sure to use white paper and print out using dark ink. If it is hard to read your essay, it will also be hard to follow your argument.
