Which |term |describes |the |most |frequently |occurring |value |in |a |data |set?
1. |mode
2. |mean
3. |range
4. |median |- |CORRECT |ANSWER✔✔-1. |mode
Why |is |it |important |to |determine |if |a |sample |is |normally |distributed?
1. |Because |larger |samples |are |usually |not |normally |distributed
2. |Because |we |cannot |run |statistical |tests |on |samples |that |are |not |normally |distributed
3. |Because |a |normally |distributed |sample |does |not |require |advanced |statistical |tests
4. |Because |it |will |determine |whether |you |can |use |a |parametric |test |or |a |non-parametric |test |- |
CORRECT |ANSWER✔✔-4. |Because |it |will |determine |whether |you |can |use |a |parametric |test |or |
a |non-parametric |test
In |reviewing |a |study's |results, |you |see |that |the |correlation |coefficient |between |chocolate |
consumption |and |exam |performance |is |r= |-0.8 |(p=.02)
What |can |you |infer |about |these |results?
1. |There |is |no |relationship |between |chocolate |consumption |and |exam |performance
2. |As |students |consume |more |chocolate, |they |perform |better |on |exams
3. |As |students |consume |more |chocolate |they |perform |worse |on |exams
4. |As |students |consume |less |chocolate, |they |perform |worse |on |exams |- |CORRECT |
ANSWER✔✔-3. |As |students |consume |more |chocolate |they |perform |worse |on |exams
Which |correctly |describes |statistical |analysis?
, 1. |This |is |an |optional |component |of |data |collection |in |quantitative |research
2. |This |is |an |optional |component |of |data |analysis |in |quantitative |research
3. |This |is |a |critical |part |of |the |data |analysis |phase |in |quantitative |research
4. |This |is |a |critical |part |of |the |data |collection |phase |in |quantitative |research |- |CORRECT |
ANSWER✔✔-3. |This |is |a |critical |part |of |the |data |analysis |phase |in |quantitative |research
A |researcher |concludes |that |a |significant |relationship |exists |between |chocolate |consumption |
and |exam |performance- |yet, |in |reality |there |is |no |significant |relationship. |This |is |also |known |as
|what?
1. |Standard |deviation |error
2. |Type |II |error
3. |Type |1 |error
4. |Correlation |coefficient |- |CORRECT |ANSWER✔✔-3. |Type |1 |error
The |center |value |of |the |data |set |is |also |known |as |what?
1. |Median
2. |Range
3. |Mean
4. |Mode |- |CORRECT |ANSWER✔✔-1. |Median
What |is |the |difference |between |inferential |and |descriptive |statistics?
1. |Descriptive |statistics |test |hypotheses, |inferential |statistics |cannot |test |hypotheses
2. |Descriptive |statistics |are |used |for |the |null |hypothesis, |inferential |statistics |are |used |for |the |
alternative |hypothesis
3. |Descriptive |statistics |provide |information |about |a |sample, |inferential |statistics |can |be |used |
to |make |predictions
