Answer Survey The other types of descriptive research are case studies and naturalistic observation Main Menu The main weakness of a case study Answer One can’t generalize from case studies because they are not representative of any larger group Main Menu They ask: What do you mean? How do you know that’s true? Is their reasoning sound? Is the evidence sufficient? Answer Skeptics Crocoduck Main Menu Examining assumptions, discerning hidden values, evaluating evidence, assessing conclusions. Answer Critical Thinking Main Menu Daily Double!!! “I knew the Packers would lose to the Vikings.” Answer The hindsight bias Main Menu Mary is the third fastest swimmer in the state but still believes she’ll win her event at state.

Answer The study can’t be done without deception and; The study is likely to uncover something important/useful to humanity. Main Menu What’s a hypothesis? Answer A specific, testable prediction Main Menu Main advantage(s) of a case study Answer The richness and depth of case studies create understanding and may foster new hypotheses. Main Menu Jane Goodall’s research method Answer Naturalistic Observation Main Menu Describe how you would conduct a study to determine what percent of Wisconsin teachers own a Toyota. Answer Identify all Wisconsin teachers. This is your population. Then, randomly select enough Wisconsin teachers to get a representative sample and ask them whether they own a Toyota car. Main Menu Statistics (e.g. survey data) that can be used to generalize to a population are called ___________ statistics. Answer Inferential Main Menu Samples are drawn randomly from the _________. Answer population Main Menu In surveys, more people approve of using tax dollars to “help the needy” than for “welfare.” Answer Wording Effects (or Framing Effects) Main Menu If your sample was randomly selected, you can do this: Answer Generalize to the population Main Menu If randomly selected, your sample is… Answer Representative of the population Main Menu People think that sugar makes kids hyperactive. It doesn’t. Belief in a correlation that doesn’t exist is: Answer Illusory Correlation Main Menu If older people commit fewer crimes, age and crime are _________ correlated… Answer negatively Main Menu Two things correlations are good for… Answer Identifying possible cause and effect & Prediction Main Menu Daily Double!!!

Why? Answer The second one – because the 245 drives the mean way up! (positively skewed distribution) Main Menu What are the mode and range for the scores below? 20 20 20 65 66 171 200 Answer Mode: 20 Range: 180 Main Menu If vehicle weight is distributed normally, with a mean of 3500 lbs. and a standard deviation of 500 lbs., what percent of vehicles lie between 2500 and 4500 lbs.? Answer About 95% Main Menu If women’s height is normally distributed with a mean of 64 inches and a standard deviation of 4 inches, what percent of women are between 52 and 76 inches tall? Answer About 99.7% Main Menu As the difference between means in an experiment goes up, the calculated alpha level goes _______. Answer Down – alpha gives an estimate of the likelihood that the observed difference between the means happened by chance. Larger differences are less likely to be due to chance. Main Menu What is on the y-axis and how would this distribution be described? Answer Number of scores is on the y-axis & Negatively-skewed Main Menu Which is likely to have the larger standard deviation? The heights of Swedish adults, or the heights of European adults? Explain. Answer European, because there is more variability in more racially and ethnically diverse groups. Main Menu Daily Double!!! Describe how to make a scatterplot, and how to make a histogram. Answer Scatterplot has two variables. Histogram has one, with number of cases on the y-axis. Main Menu Name two measures of variability… Answer Standard deviation, and range. Main Menu Assume the number of homicides in Milwaukee per year was between 40 and 50 from 2008-2014, and then 74 in 2015. What would you expect to happen to homicides in 2016? Explain… Answer Go down – regression to the mean Main Menu Self-esteem and number of sexual partners are negatively correlated in female teens, and yet, raising teens’ self-esteem hasn’t been shown to reduce the number of sexual partners. Explain… Answer It’s just a correlation! Main Menu Why is random assignment essential in experimentation? Answer Only if the groups are very similar at the start can we have confidence that the difference between the groups at the end on the DV is due to the IV. Main Menu If you take ibuprofen for a headache and your headache improves, you don’t know that it worked. Explain… Answer No control group. You don’t know if it would have gotten better on its own, or if the placebo effect cured it.

ANSWER It means the difference was unlikely to be due to chance.
