How did you calculate LD50?
Calculating the median lethal dose, LD50 (the dose of a toxin which kills half of the test population) first requires a lot of laboratory testing which can take months. The data is then accumulated and manipulated to give a value which is the median dose. -- Why don't you get to understand Lichfield wilcoxon's method.
What is a math typical value?
The mean is that value that is most commonly referred to as the average.The typical value is a synonym for the mean and average.The typical value is the mean.
What does a negative z-score mean?
z-score of a value=(that value minus the mean)/(standard deviation). So if a value has a negative z-score, then it is below the mean.
Why is the mean an estimated value and not the true value?
The mean can be a true value. The mean height of the members of my family will be a true value.However if my family is used as a (non-random) sample to represent all humankind, the mean will not be the true value but an estimated value. The accuracy of that estimate will depend on how representative of humankind my family is - at least in their heights.
What value corresponds to the 38 percent of the data between the mean and the z value?
The value is 0.3055
What is the LD50 value for plutonium?
A probable value for plutonium is LD50 = 5 μg/kg (cumulated chemical and radiological effects).
What is the maximum amount a heroin user can use in a day?
the lethal dosis (LD50 = Lethal to 50% of the testet animals) is at 25mg /kg This is mouse-testet
What is the most dangerous LD 50 value 500 or 17.5?
An LD50 value of 17.5 milligrams would be considered far more dangerous than an LD50 value of 500 milligrams. The LD50 value for any drug or other chemical compound is the minimum lethal dose that kills 50% of test subjects (tests are usually conducted on rats and mice). Thus the lower the value, the more toxic the drug.
Why is the LD50 of a mouse different from a human's LD50?
ld50 for lamotrigine
How do you know how powerful a poison is?
The strength of a poison is determined by its LD50 value (Lethal Dose). The LD50 value is the amount of toxin it takes to kill 50 percent of a population each time a dosing experiment is done in a lab setting. The value is measured by mg/kg of body weight. For example, the LD50 value of salt is 1000 mg.kg body weight, that means that every kg of body weight must contain 1000 mg of salt in it to cause death. The lower the LD50 value, the more potent or deadly the poison is. Remember that death is not the only end point measured in toxicology. There are many poisons that cause severe adverse effects well before they kill someone. Someone may experience things such as paralysis or cognitive disruption at levels much below the LD50 value, and some poisons take much larger doses to cause effects than others. Remember, the dose defines the poison, but the power of the poison is measure technically by the LD50 value.
What is the formula used in calculation of ld50 of a substance?
LD50 ('50%-Lethality' dose) is a meaured value from many statical investigations. So there's only a good definition on how it should be 'measured' and can not be calculated from other values by formula.
What does Ty mean in Afrikaans?
Heroin
Is neurontin a form of heroin?
no neurontin is gabapentin and has no recreational value
What does 'LD50' stand for?
LD50 stands for Lethal Dose 50, a measurement of how much exposure it takes to a certain chemical to kill 50% of a target population. This is usually a calculated value based on lab exposure of the chemical to a population of animals.
What is the ld50 of thiopental?
thipental
Why do cockroaches survive a nuclear bomb?
The radiation LD50 of most insects is far higher than the LD50 of mammals.
What does LD50 measure?
LD50 (short for lethal dose 50) is the dose of a substance at which it kills 50% of test subjects.
