Can normal distribution be used if the data is not normal?
You can use a normal distribution to approximate a binomial distribution if conditions are met such as n*p and n*q is > or = to 5 & n >30.
What does it mean normal distribution?
The Normal distribution is a probability distribution of the exponential family. It is a symmetric distribution which is defined by just two parameters: its mean and variance (or standard deviation. It is one of the most commonly occurring distributions for continuous variables. Also, under suitable conditions, other distributions can be approximated by the Normal. Unfortunately, these approximations are often used even if the required conditions are not met!
When does normal distribution occur?
The normal distribution occurs when a number of random variables, with independent distributions, are added together. No matter what the underlying probability distribution of the individual variables, their sum tends to the normal as their number increases. Many everyday measures are composed of the sums of small components and so they follow the normal distribution.
What are the normal sequence of steps in formulating diagnosis?
obtaining medical history, performs physical, obtain diagnostic studies and laboratory test, compare with normal findings, integrate and interpret, formulate diagnosis, treatment plan, prognosis and prevention, provide patient teaching, pertinent information and make appropriate referrals.
What is the difference of a normal distribution and a stardard normal distribution?
The standard normal distribution is a special case of the normal distribution. The standard normal has mean 0 and variance 1.
Simplest forms of matter that can exist under normal laboratory conditions?
Simplest forms of matter that can exist under normal laboratory conditions is elements. A mixture is a physical blend of 2 or more substances.
Simplest form of matter that can exist under normal conditions?
Elements
Substance that cannot be changed into a simpler substance under normal laboratory conditions?
Substance that cannot be changed into a simpler substance under normal laboratory conditions are elements. A physical blend of two or more substances that are not chemically combined is a mixture.
What are the simplest forms of matter that can exist under normal laboratory conditions?
This question is subjective. That would probably be a single photon. Although photon is energy, due to the mass-energy equivalence principle, you can consider a photon to be matter. It is affected by gravity. An electron is also a fundamental particle that can be easily produced in the lab. It has a reast mass (and a negative charge).
What is the state of matter of hydrogen?
Hydrogen is a gas in normal conditions.
What state of matter is shaving cream?
In normal conditions the shaving cream is a solid.
What state of matter is nitrogen?
Under normal conditions - the ones we are accustomed to - it is a gas.
What culture media do treponema pallidum grow on?
Treponema pallidum is not grown under normal laboratory conditions, but in rabbit testes.
What state of matter is bromine?
Bromine is one of only two elements that is a liquid under normal conditions.
Where could you find plasma the fourth state of matter?
Mainly in stars - thus, the plasma state is the most common state of matter in the Universe, at least when talking about baryonic (i.e., "normal") matter.Also, under laboratory conditions it's possible to heat matter to the point of becoming a plasma.
What is the state of matter of chorine?
Under normal conditions, chlorine is a gas. It occurs naturally as Cl2, and it has a yellowish color to it.
How well does water dissolve salt or sugar compared to other liquids?
Water would be the best solvent compared to other liquids in normal household/laboratory conditions.
