| Strengths: |
Accurate computation if student does not have statistical analysis program such as SAS or SPSS. Could be added to course using Excel for analysis since Excel does not do 2X2X2 ANOVA. The website uses correct notation in tables and interacting terms and is visually appealing and easy to follow. |
| Concerns: |
There seem to be little to no instructions as to what an ANOVA model would be used for. The user must come with a decent background of knowledge to get out of this module the use intended. It does not seem to include any explanatory material nor even explain that there are ANOVA models other than a three-way and how they are related. |

Potential Effectiveness as a Teaching Tool |
Rating:     |
|
| Strengths: |
The website is easy to use and you can receive immediate feedback and analysis that are understandable with previous knowledge. If students were give a data set, they could enter it to get the ANOVA table. |
| Concerns: |
The module does not promote student understanding of the concepts. There are no explanations of how any of the calculations are done behind the scenes with the data given. Students are not challenged with this tool and if an instructor wanted to use it for assignments, they would need to manipulate the information given to assess any student learning to avoid students simply writing down the table, yet having little to no understanding of the concepts presented. |

Ease of Use for Both Students and Faculty |
| Rating: |
|
| Strengths: |
This module is very easy to use, has clear instructions and is interactive with the user. |
| Concerns: |
The user must come with previous background information and knowledge to be able to effectively use this module, and it may not be as engaging as it is easy and quick to use. |
|
|
| Other Issues and Comments: |
Students enter data and the ANOVA table is output. If students are using other statistical package (such as SAS or SPSS), there would be no reason to include it in the course. |
