  3. Validity--$100 • The extent to which a researcher can generalize findings to the population • answer

  4. Validity--$200 • The extent to which a researcher can draw a single, unambiguous conclusion from the results • answer

  5. Validity --$300 • A study is said to be _______ when an extraneous variable is allowed to vary along with the independent variable. • answer

  6. Validity --$400 • An ______ variable is a variable that is not being directly studied, but has the potential of changing along with the independent variable. • answer

  7. Validity -$500 • Although tight control over extraneous variables gives you high levels of _____, it may result in low levels of _____. • answer

  8. Strategies & Designs--$100 • The goal of this research strategy is to describe a variable as it exists naturally. • answer

  9. Strategies & Designs --$200 • The goal of this research strategy is to describe the relationship between two variables as they naturally occur in the environment. • answer

  10. Strategies & Designs --$300 • A researcher joins a religious cult in order to observe the behaviors of the members. The researcher is using _____ observation. • answer

  11. Strategies & Designs --$400 • This type of research design can be useful for studying unusual clinical cases such as brain injuries. • answer

  12. Strategies & Designs --$500 • A researcher systematically varies the amount of caffeine in cola (0, 10, and 20 mg) and observes that his participants’ anxiety levels increase as caffeine amount increases. The 0-mg condition is called the __________. • answer

  13. Frequency Distributions--$100 • The simplest frequency distribution consists of these two columns. • answer

  14. Frequency Distributions --$200 • The shape of a _____ distribution is perfectly symmetrical. • answer

  15. Frequency Distributions --$300 • This is the appropriate type of chart (or visual) for discrete data. • answer

  16. Frequency Distributions --$400 • These two types of charts appropriately represent data from continuous variables. • answer

  17. Frequency Distributions --$500 • A mathematical procedure for estimating a value that is located between two known values. • answer

  18. Descriptive Stats--$100 • A statistical measure that determines a single value that accurately describes the typical score of a distribution. • answer

  19. Descriptive Stats--$200 • This measure of central tendency is the score at the 50th percentile. • answer

  20. Descriptive Stats --$300 • This measure of variability measures the average distance between scores and the mean. • answer

  21. Descriptive Stats --$400 • This measures the average of the squared distances from the mean. • answer

  22. Descriptive Stats --$500 • In order to calculate this, take the square root of the population variance. • answer

  23. Grab Bag--$100 • The type of correlation that indicates an inverse relationship between two variables. • answer

  24. Grab Bag--$200 • In statistical formulas, N represents ______________. • answer

  25. Grab Bag--$300 • The only appropriate measure of central tendency for data measured on a nominal scale. • answer

  26. Grab Bag--$400 • Percentile ranks correspond to the values in the ______ column of a frequency distribution • answer

  27. Grab Bag--$500 • The sum of the deviations from the mean always equal this. • answer
