Hi Kathy,

Thanks, could you provide a short description of the additions you provide and maybe indicate how they may influence the sampling?
Kindest regards,

Eric

Subject: Parameters of the sample size

Dear all,

Yesterday, we discussed the parameters that influence the size of the sample. I would like some more input on that in the form of a list of parameters including a short description and how they influence the sample size.

Very generally we already have (numbering is random and does not mean anything, but easy for the discussion and overview):

1. Required level of confidence
2. Size of the website
3. Complexity of the website
4. Number of states and resulting increase of number of web pages as a result of that 5. Heterogeneity or homogeneity of the website/web page code 6. Level of detail of the report 7. please add here

Not all of them in the document yet. Can we think of more? If you want to help, please add short descriptions and how they influence the work/choices of the evaluator.

Am I missing anything?

Eric
