What sorts of limitations (i.e. LATE, attrition) do you expect for the experiment?
What can be done to mitigate the effects of those problems?

Expert Solution

Attrition bias happens when participants drop out from a study; The drop-outs have unique study-related characteristics, resulting in a difference between initial and ending samples. Selective attrition bias happens when the differences are between control groups and treatment groups (as opposed to beginning and ending samples). If the study-related characteristics are completely random with no systematic pattern, then attrition bias does not happen.

Effect on Validity

Missing or incomplete outcome data due to attrition bias can weaken internal validity and external validity. Weakened internal validity means that the interactions between the study variables (i.e. the variables i your experiment or study) are changed and may even become meaningless. For example, correlations may be found where there are none, or important correlations may be missed entirely. Weakened external validity means that the study cannot be generalized to other populations.

You didn't clearly mention what would be the experiment. Also I have no option for replying if you comment the question. Please repost it if further assistance is needed.

1. What sorts of residues (i.e. what amino acid side chains) would one expect to find on the surface of a protein with an unusually high isoelectric point (e.g. 9.5). What if the pI were unusually low (e.g. 3.4)? 2. When one talks about “protein-ligand” interactions, what sorts of molecules can be “ligands?” 3. How would you explain the conformational selection model of protein-ligand interactions to an educated lay person?

Increasingly, patients expect full access to their EMRs and EHRs, What limitations, if any, would be in the best interest of patients? For example, should healthcare providers have access to new test results for 3 full business days before these are posted for patient viewing?
