What is statistical control?
A statistical technique used to eliminate variance in dependent variables caused by extraneous sources. In evaluation research, statistical controls are often used to control for possible variation due to selection bias by adjusting data for program and control group on relevant characteristics.
Are all vaccines caused by antibody production and give lifetime immunity true or false?
False, because not all vaccines provide lifelong immunity. Some require boosters or reimmunization.
What are the most common causes of car accidents in Australia?
Car accidents are caused by many things but the main cause of accidents are speeding drivers.Statistics show that 40% of the accidents worldwide are caused by speeding. The other reasons being distracted drivers (26%) and drunk drivers (34%)All sources are governmental prooven
What is the compass variation?
I think you're after the magnetic variation. If so :- That is the variation between true north and the earth's magnetic field at your location. Can be + or - and up to a few tens of degrees.Your compass does not actually point to north, though that is a useful assumption. In reality, the compass needle aligns itself with the direction of the earth's magnetic lines of force at your location. These do not run nicely north and south. Your map will have on it an indication of the magnetic variation in that region, and may include also the amount by which that varies annually.The earth's magnetic field is generated (most of it anyway) by electrical currents flowing in the magma. These currents may be caused by the core rotating slightly faster than the mantle and crust. [But no one's been there!] The magma and the earths core beneath it are much too hot to sustain a magnetic field.
What probable cause of Robert Wadlow's condition?
Robert Wadlow, known as the tallest person in history, had a condition called hyperplasia of the pituitary gland. This condition caused an excess production of growth hormone, leading to his abnormally tall stature.
Process is in control the variations in x-bar and r between different samples of the process output are caused by which assignable causes natural variations sampling bias human error?
If the process is in control, then the variation is termed common cause or what you have stated as natural variation.
What causes the variation in pitch?
it is caused when the variation is hit on the guitar
What causes varation in traits?
Genotypic variation is caused by mutation. Phenotypic variation can be caused by mutation, which gives rise to different alleles, or it can be caused by environmental factors.
What is variation in evolution?
A variation of a gene is called and allele. Different alleles are caused by mutations.
What is variation caused by?
It is caused by crossing over in sexual reproduction and random mutations in DNA.
Natural selection causes changes in populations of organisms not individual organisms because?
differential reproductive success caused by genetic variation is necessary for the process of natural selection.
Global pressure belts are caused by?
Temperature variation.
What is the observation of a wet spot on a hot highway in the summer caused by?
This is caused by refraction. A variation in air density corresponds to variation in refractive index of the air, locally near the road.
How fast does a musket fire?
Usually 200-400 metres per second. The variation is caused by the bad process in which muskets were made at the time. The latter number is more around today's muskets.
Is it true that seasonal variation is caused by the earth's eliptical orbit around the sun?
No, it is not.
What caused variation?
Cross pollination, mutation and polyploidy lead to variations in the progeny
What are the political obstacles in trying to reduce acid rain?
Most pollution is caused by the production and use of energy sources. Reducing acid is difficult because the industries causing it have considerable influence in politics.
