Solutions
Expert Solution
The assumptions of ANOVA are described as under:
The experimental errors of the data are normally distributed.
This implies that if one were to repeat the study various number of
times, and calculate the mean, the means would be normally
distributed.
Equal variances between treatments. The different treatment
conditions in the study should have more or less equal
variances.
Independence of samples. This refers to the assumption that the
samples are randomised or come from a random sample design.
a)Describe what each one of the assumptions of the model
consists of in an ANOVA and explain the typical way in which these
assumptions are verified.

ANOVA?
Explain how variance is partitioned in a repeated measures
ANOVA. Make sure to highlight the final three sources of variation

Question 1
One of the assumptions of the One-Way ANOVA is that the
samples for all three (or more) groups are dependent.
True
False
Question 2
One of the assumptions of the One-Way ANOVA is that the
samples are from a normal distribution.
True
False
Question 3
Sum of Squares Between + Sum of Squares Within = Sum of
Squares Total
Breaking the Sum of Squares Total up into
SSBetween and SSWithin is called
____________________ the sum of squares.
answer...
1. a. Explain what PPP is, what it assumes, why these
assumptions mean it may not hold in the real world, and when it
tends to hold and why. Discuss crucial reasons it will tend to
break down.
b. Explain what the Real Exchange Rate is, and how it is
different from PPP. What is the implication for the Real Exchange
Rate if PPP holds? Explain why. Please answer all parts!!!!!!
