Question 1
The median elevation of sites is
7.90 m
8.25 m
8.45 m
9.03 m
Question 2
What is the shape of the elevation distribution?
Skewed to the right
Symmetric with outliers
Skewed to the left
Symmetric
Question 3
The distribution of cadmium concentration appears to be skewed to the right. The researchers decided to first log-transform these concentration values, to make the distribution more symmetric, giving the variable LogCadmium. What is the mean of this transformed variable for the sites used for growing fruit trees?
-0.0970
-0.0243
0.1100
0.9190
Question 4
The researchers wanted to know if there is a difference in the mean cadmium levels between the different land uses. What are the residual degrees of freedom in the one-way ANOVA to address this question?
2
67
68
69
Question 5
Based on the log-transformed concentration values, what is the total sum of squares for the one-way ANOVA to compare land uses?
4.688
16.896
21.584
32.376
Question 6
Based on the F test for the one-way ANOVA to compare land uses, you can conclude that there is
no evidence to suggest that there is a difference in mean log-transformed cadmium concentration between the different land uses (p > 0.1)
weak evidence to suggest that there is a difference in mean log-transformed cadmium concentration between the different land uses (p < 0.1)
moderate evidence to suggest that there is a difference in mean log-transformed cadmium concentration between the different land uses (p < 0.05)
strong evidence to suggest that there is a difference in mean log-transformed cadmium concentration between the different land uses (p < 0.01)
Question 7
What is the R2 value for this one-way ANOVA model?
0.0472
0.2172
0.2774
0.4660
Question 8
The researchers also wanted to know if there is a difference in the mean log-transformed cadmium levels between the three different flooding frequencies. What are the degrees of freedom for the Flooding factor in the one-way ANOVA to address this question?
1
2
67
69
Question 9
What is the F statistic for the one-way ANOVA model to compare flooding frequencies?
5.37
9.29
22.52
51.72
