The most important distinction of an experimental study design compared with a non-experimental or observational study design is the exposure assignment. One example of this would be randomizing one group of patients to get the new breast cancer chemotherapy drug and the other group of patients to receive the current standard chemotherapy drug.
The intraserial precisicion (the correct term should be imprecision) is done best ba using at least 2 (better three samples), covering the lower, median and upper measurement range of your assay.
A special case of a CATEGORICAL variable is a DICHOTOMOUS VARIABLE. DICHOTOMOUS variables have only two CHARACTERISTICS (male or female). When naming QUALITATIVE variables, it is important to name the category rather than the levels (i.e., gender is the variable name, not male and female).

Using Microsoft Excel to plot and apply standard curve A protein assay, such the BCA Protein Assay, is an excellent tool for estimating the protein concentration of a sample. The intensity of the colored reaction product is a direct function of protein amount that can be determined by comparing its absorbance value to a standard curve.
Experimental Design Treatment group vs. control group A single comparison Experimental efficiency Perhaps we want to look at who makes the cappuccino (Seattle’s, Starbucks, Pete’s) as well as the difference between coffee and cappuccino. 2X3 Factorial Interaction effects.
