IC 50 values are typically expressed as molar concentration. IC 50 is commonly used as a measure of antagonist drug potency in pharmacological research. IC 50 is comparable to other measures of potency, such as EC 50 for excitatory drugs. EC 50 represents the dose or plasma concentration required for obtaining 50% of a maximum effect in vivo. [1]
The pharmacological definition cannot apply to these substances because utilization and absorption is a function of the nutritional status and physiological state of the subject, [10] resulting in even greater differences from individual to individual (inter-individual variation). Therefore, bioavailability for dietary supplements can be ...
For example, to make 100 mL of 50% alc/vol ethanol solution, water would be added to 50 mL of ethanol to make up exactly 100 mL. Whereas to make a 50% v/v ethanol solution, 50 mL of ethanol and 50 mL of water could be mixed but the resulting volume of solution will measure less than 100 mL due to the change of volume on mixing, and will contain ...
Instead of using scales of 0 to 100%, the scale .000 to 1.000 is commonly used. A higher field goal percentage denotes higher efficiency. In basketball, a FG% of .500 (50%) or above is considered a good percentage, although this criterion does not apply equally to all positions. Guards usually have lower FG% than forwards and centers. Field ...
[31] [32] The Urban-Brookings Tax Policy Center found that the bottom 20 percent of earners pay an average 2.9 percent effective income tax rate federally, while the richest 1 percent paid an effective 29.6 percent tax rate and the top 0.01 percent paid an effective 30.6 percent tax rate. [33]
Profit margin is calculated with selling price (or revenue) taken as base times 100. It is the percentage of selling price that is turned into profit, whereas "profit percentage" or "markup" is the percentage of cost price that one gets as profit on top of cost price.
The second quartile (Q 2) is the median of a data set; thus 50% of the data lies below this point. The third quartile (Q 3) is the 75th percentile where lowest 75% data is below this point. It is known as the upper quartile, as 75% of the data lies below this point. [1]
