  1. 4. quantified sampling error
  2. 6. One part of this theorem tells us that as sample size increases, our sampling error decreases.
  3. 8. When we plot error bars in bar charts, we should NOT use the standard ________.
  4. 11. The population SD is 3. If we take repeated samples of sample size 36, we would expect the standard error to be ______ (spell out all numbers).
  5. 12. Strumila et al., 2019. Estimate the standard error of perfectionism at pre-session (found in table 1).
  6. 15. Grace got the TFs to play Pokemon Go. Ben caught 41 pokemons. Hannah caught 25 pokemons. Meg caught 22 pokemons. Yiqiao caught 35 pokemons. Shuchen caught 32 pokemons. Cole caught 15 pokemons. Mohammad caught 14 pokemons. Adrian caught 16 pokemons. What is the sample size of data from Ben?
Down
  1. 1. truee/false Sampling errors occur because the researcher made a mistake while collecting a sample
  2. 2. In Table 1 of Martin et al., 2021 on Green light exposure and pain, the researchers reported standard ____ along with the mean. This is a good/bad model of how we are supposed to report descriptive statistics.
  3. 3. In Table 1 of Strumila et al., 2019 on the safety and efficacy of tDCS in patients, they reported ______ along with the mean, and this is a good example of how we should report descriptive statistics from our sample.
  4. 5. truee/false Standard error is ALWAYS smaller than the standard deviation.
  5. 7. Grace got the TFs to play Pokemon Go. Ben caught 41 pokemons. Hannah caught 25 pokemons. Meg caught 22 pokemons. Yiqiao caught 35 pokemons. Shuchen caught 32 pokemons. Cole caught 15 pokemons. Mohammad caught 14 pokemons. Adrian caught 16 pokemons. How many total observations (i.e., pokemons) are on the record?
  6. 9. Reporting SE instead of SD alongside the mean in descriptive statistics is problematic because it is _______ the readers into thinking that the variation is much smaller than it actually is.
  7. 10. Grace got the TFs to play Pokemon Go. Ben caught 41 pokemons. Hannah caught 25 pokemons. Meg caught 22 pokemons. Yiqiao caught 35 pokemons. Shuchen caught 32 pokemons. Cole caught 15 pokemons. Mohammad caught 14 pokemons. Adrian caught 16 pokemons. How many samples of pokemons are there?How many samples of pokemons are there?
  8. 13. When sample size increases, the spread becomes narrower and the estimate becomes more _______.
  9. 14. The sampling distribution of sample standard deviation is going to look _______ when the underlying population distribution is skewed.
