Week 3 Paired T-cupel and ANOVA
For this week's operation, frequently be confident to avow the trifling and vacillate hypotheses and use alpha = 0.05 for our determination value in the discard or do not discard determination on the trifling conjecture.
1. Many companies investigate the degree midsharp-end to be the "bargain objurgate" - the compensation demanded to employ a new employee.
Does the order, on mediocre, pay its corporeal employees at or aloft the bargain objurgate? Salary Midsharp-end Diff
Use the axioms columns at the fair to set up the paired axioms set for the anatomy.
Null Hypothesis
Alt Hypothesis
Statistical cupel to use:
What is the p-value:
Is P-value < 0.05 (one bottom cupel) or 0.25 (two bottom cupel)?
Do we REJ or Not discard the trifling?
If the trifling conjecture was discarded, what is the commodities largeness value:
If adapted, what is the sense of commodities largeness measure:
Interpretation of cupel results:
Let's contemplate at some other factors that jurisdiction govern pay - education(degree) and accomplishment ratings.
2. Last week, we set-up that mediocre accomplishment ratings do not vary betwixt males and females in the population.
Now we demand to see if they vary unordered the degrees. Is the mediocre performace rating the selfselfsimilar for all degrees?
(Assume estrangements are correspondent athwart the degrees for this ANOVA.)
The rating values arranged by degree bear been placed in columns I - N for you.
Null Hypothesis: Ho: instrument correspondent for all degrees
Alt. Hypothesis: Ha: at lowest one balance is unequal
Place B17 in Outcome ramble box.
Interpretation of cupel results:
What is the p-value:
Is P-value < 0.05?
Do we REJ or Not discard the trifling?
If the trifling conjecture was discarded, what is the commodities largeness value (eta squared):
Meaning of commodities largeness measure:
What does that determination balance in conditions of our correspondent pay question:
3. While it appears that mediocre salaries per each degree vary, we demand to cupel this arrogance.
Is the mediocre compensation the selfselfsimilar for each of the degree smooths?
Use the input board to the fair to roll salaries lower each degree smooth.
(Assume correspondent estrangement, and use the anatomy toolpak part ANOVA.)
Null Hypothesis:
Alt. Hypothesis:
Place B51 in Outcome ramble box.
Interpretation of cupel results:
What is the p-value:
Is P-value < 0.05?
Do we REJ or Not discard the trifling?
If the trifling conjecture was discarded, what is the commodities largeness value (eta squared):
If adapted, what is the sense of commodities largeness measure:
Interpretation:
4. The board and anatomy adown demonstobjurgate a 2-way ANOVA after a while response. Please understand the results.
Ho: Mediocre compas by gender are correspondent
Ha: Mediocre compas by gender are not correspondent
Ho: Mediocre compas are correspondent for each stage
Ha: Mediocre compas are not correspondent for each stage
Ho: Interaction is not significant
Ha: Interaction is significant
Perform anatomy:
Interpretation:
For Ho: Mediocre compas by gender are correspondent Ha: Mediocre compas by gender are not correspondent
What is the p-value:
Is P-value < 0.05?
Do we REJ or Not discard the trifling?
If the trifling conjecture was discarded, what is the commodities largeness value (eta squared):
Meaning of commodities largeness measure:
For Ho: Mediocre compas are correspondent for all stages Ha: Mediocre compas are not correspondent for all degrees
What is the p-value:
Is P-value < 0.05?
Do we REJ or Not discard the trifling?
If the trifling conjecture was discarded, what is the commodities largeness value (eta squared):
Meaning of commodities largeness measure:
For: Ho: Interaction is not significant Ha: Interaction is significant
What is the p-value:
Is P-value < 0.05?
Do we REJ or Not discard the trifling?
If the trifling conjecture was discarded, what is the commodities largeness value (eta squared):

5. Using the results up thru this week, what are your conclusions environing gender correspondent pay for correspondent operation at this sharp-end?
