This chapter will cover. The use of statistical evidence in arguments. The reporting of statistical data. The use of causal generalizations. Inductive Reasoning. Inductive Reasoning. Evidence offers strong support ‘beyond a reasonable doubt’. 6.1 Large Sample Confidence Intervals for a Mean. A confidence interval for a parameter is a data-based interval of numbers likely to include the true value of the parameter with a probability-based confidence.. Using Lock5. Statistics: Unlocking the Power of Data. Patti Frazer Lock. Chapter 1: Collecting Data. Why is this first?. Comes first in actual analysis. More interesting than histograms and mean/median!. Chapter 8. Hyde, Fennema & Lamon (1990). Mean gender differences in mathematical reasoning were very small.. When extreme tails of the distributions were removed, differences were smaller and reversed direction (favored girls). 6.1 Large Sample Confidence Intervals for a Mean.

Chapter 6 Confidence Intervals Sections 6-1 and 6-2 Confidence Intervals for Large and Small Samples   VOCABULARY: Point Estimate – A single value estimate for a population parameter. Example: . Suppose you wanted to test the drug that may affect IQ, but this time you look for changes within each subject. This is done by measuring the IQ for each subject before and after taking the drug. For 9 subjects, you might get a result like this: . Diogo. Bolster. Laminar or Turbulent Flow. Turbulent Flow http://. www.youtube.com/watch?v. =NplrDarMDF8.
