Experimental Hypotheses and Variables

1. 1Complete the 7 steps to the scientific method:
   1. Identify the problem and make an observation
   2.
   3.
   4. Conduct experiment
   5.
   6. Communicate results and/or form a theory
   7. Repeat

   1. AParsimonious
   2. BPrecise
   3. CFalsifiable
   4. DComplicated
   5. ELong-winded and wordy
   6. FThe only possible explanation
7. 7What is parsimony?

   1. AWhen a theory has less assumptions and can be explained in a single sentence
   2. BWhen a theory has a lot of assumptions and can be explained in an essay
8. 8Hypotheses are defined as...

   1. APredictions from theories about what we expect to find
   2. BTheories from predictions about what we expect to find
9. 9Hypotheses can be experimental/scientific/alternate. What are the two sub-types of these hypotheses?

   1. ADirectional and non-directional
   2. BDirectional and null
   3. CNull and non-directional
10. 10Non directional hypotheses state the exact expected direction of results

    1. ATrue
    2. BFalse

11. 11The null hypothesis...

    1. AStates a relationship
    2. BStates no relationship
12. 12The null hypothesis is always assumed to be...

    1. ATrue
    2. BFalse
13. 13Name three things that can go wrong in an experimental situation

    1. AExperimenter error
    2. BType I error
    3. CType II error
    4. DParticipants drop out
    5. EExperimenter gives up
14. 14Define a Type I error

    1. AWe reject the null when it is true
    2. BWe accept the null when it is false
15. 15An experiment must have testable hypotheses that...

    1. ASpecify the nature of the relationship
    2. BState or imply measurability
    3. CAre unclear as to the nature of the relationship
    4. DHave no sign of measurability
16. 16Name 2 other reasons why hypotheses are generated...
    To replicate or extend previous results
    To solve practical problems

    1. ATo test a theory
    2. BTo satisfy curiosity
    3. CTo make people sound clever
17. 17The independant variable is the one that is manipulated

    1. ATrue
    2. BFalse
18. 18Confounding variables...

    1. AWholly or partially account for the relationship between two other variables, and change systematically with the IV while affecting the DV
    2. BParts of the DV that affect the IV
    3. CHave no effect at all
19. 19A variable is defined as a property of an object or event that takes on different values

    1. ATrue
    2. BFalse
20. 20Measurement is...

    1. AThe process of giving participants categories or values of the variable being manipulated
    2. BThe process of recruiting participants
    3. CThe process of ethical approval
21. 21The type of scale used can affect the type of statistical analysis used later on, and the conclusions drawn from the study. These scales are nominal (category labels), ordinal (fixed order of scores), interval and ratio. What is the difference between interval and ratio data?

    1. AInterval is continuous and the intervals between points matter, whereas ratio is continuous but has a true zero point, for example length and weight
    2. BInterval is continous but ratio is not
    3. CThe intervals in ratio data matter
    4. DInterval data has a true zero point
