Exam 3 Flashcards
1
Q
Factor
A
- The independent variable of interest
2
Q
Treatment
A
- Different levels of a factor
3
Q
Single-factor experiment
A
- An experiment involving only one factor with k treatments
4
Q
Response Variable
A
- The dependent variable of interest
5
Q
Experimental Units
A
- The objects of interest in the experiment
6
Q
Completely randomized design
A
- An experimental design in which the treatments are randomly assigned to the experimental units
7
Q
Randomization
A
- The treatments should be randomly assigned to the experimental units
8
Q
Repliction
A
- Each treatment should be applied or assigned to multiple experimental units
9
Q
MSTR
A
- Called the mean square due to treatments
- Our between-treatments estimate of variance
10
Q
MSE
A
- Called the mean square due to error
- Our within-treatments estimate of variance
11
Q
Recall
A
- When the between-variance is much greater than the within-variance, the population means are probably not the same
12
Q
F distribution
A
- The F distribution is skewed to the right
- Frequently used when the test statistic is a ratio
- Shape determine by 2 degrees of freedom; 1 for the numerator and 1 for the denominator
13
Q
LSD
A
- Least Significant Difference
