STAT 5023 SAS Assignment #3
In a wildlife study three species of frogs indigenous to an area are studied. All of the pond locations are randomly selected for the study. At each location, clutches (group of eggs laid by a single female) of frog eggs are put in one of two types of floating containers. The researcher plans that at each location, there is a container of each type for each of the species of frogs. The hatched juveniles from each clutch have several response variables measured. One of those response variables appears in the table below.
| Type 1 | Type 2 | ||||
| Location | Species | Response | Location | Species | Response |
| 1 | 1 | 75.46158 | 1 | 1 | 51.505501 |

Using SAS,
- Analyze the above data in two
- First, produce expected mean squares for this
- Second, analyze this data producing REML estimates of the variance Identify these variance component estimates.
- Interpret the fixed effects. Include the least squares means and conduct the appropriate multiple comparisons using Fisher LSD type methods. Using α = 0.05, write a brief but well written paragraph of your conclusions. As always, cite the test statistic and observed significance level where necessary. Following your complete conclusions, include the
final copy of your final SAS program, copy and paste the final log after the program, and finally copy and paste the final version of the Results Viewer. All of this will be assembled in a single document (MS Word or equivalent). Upload this document to Canvas by the due date indicated.
