MAT 151 M6A2 20 Points Your response to this assignment

MAT 151 M6A2 20 Points Your response to this assignment should be a minimum of 3 pages, double-spaced, in 12-point font and should be clear, accurate, precise, and in-depth.. You must list your sources (Web site addresses, etc.) either throughout your paper or at the end. As a first step to this assignment, compose a paragraph where you state what you already know about the topic of IQ (intelligence quotient). State instances where you have used the term or have heard/seen it used. As a conclusion to the paragraph, tell some things that you don't specifically know about the topic, but would like to find out. Research the variable IQ (intelligence quotient). What is it? What does it mean? How is it measured? Is there a scale involved? When is it measured? Does a person's IQ change over time? Is IQ a continuous or discrete variable (explain why). Come to understand the concept. What is the current mean IQ? Are there any discrepancies in the reporting of this value? What do you think might be the cause of such discrepancies? What is the standard deviation? Interpret/explain what this value means. Are there any discrepancies in the reporting of this value? What do yo think might be the cause of such discrepancies? Do IQ scores have a normal distribution? Statistically, what is the significance of this? What IQ value would be represented by three standard deviations above the mean? (Mean + 3SD's = ?) Tell which value you're using for the mean and which value you're using for the sd and why you have selected these values. Using the appropriate table in your text, determine the percentage of the population that has an IQ greater than 140. Show the work (z-score conversion, etc.). Cross-reference your calculated value with what the research says. How close are the values? What might be a cause for any discrepancy? Discuss how certain IQ values classify people into categories. What are the implications for such labels?
