Why is the median more robust for extreme values?
The median is the middle of average of the middle two values from the ordered set of observations. If the extreme values are genuine then they will have no effect on the median. If they are incorrectly measured or recorded data then they may affect the position of the middle of the ordered set of data. However, since there can only be a small number of outliers, their effect on the median will be small.
What is starvation in DBMS?
Starvation refers to the use of all resources. As an example a poorly constructed database, poor concurrency controls will result in dbms starvation as usage increases. In effect the database subsystem is STARVING for resources because all available resources are being consumed. As a result you will see a severe degrade in performance.
Is this a probability or statistic the incidence of a particular side effect of a new drug is 15 percent?
It is a probability; probability of side effect is .15 and probability of no side effect is .85.
What can be used to show a cause and effect between two variables?
A controlled experiment can be used to show a cause and effect relationship. ex: an experiment studying the effect of a certain medicine on patients.
Correlational study is it cause and effect?
No correlational study is not cause and effect because correlation does not measure cause.
What is inverse sublimation?
Anything is inverse when its it becomes larger when its counterpart becomes smaller. Thus, in effect, the effect of inverse will be opposite of that of its counterpart. Inverse sublimation thus can be imagined as overgrowth of its counterpart reducing the possibility of sublimation.
What is the effect of dividing a big particle into smaller ones on the total exposed surface area?
The total surface area increases.
How does mass effect velocity?
It doesn't. But velocity does effect mass : as velocity increases, mass increases.
What is the effect of distance from an object on parallax angles?
The parallax should get smaller and harder to notice although in astronomy there are techniques used to find the parallax of stars by using the Earth's position around the sun to find the distance of the stars.
What effect does crushing have on solution rate?
Crushing sugar into smaller particulates INCREASES the rate at which the sugar will dissolve because the water can act on a larger overall surface area.
What is tha effect of unemployment?
Many people loose there jobs, and it becomes harder to find another job due to the Recession that is hitting smaller companies hard.
What effect does does a keystone predator have on its habitat?
It increases niche diversity
What is the effect on the detector if the thickness of the tire cord increases in the monitoring system?
If the length of the tyre increases the resistance increases
What is the anwer for an extreme exaggeration for effect?
A hyperbole
What is the effect of particle size on the rate of dissulution of a solute?
Smaller particle size increases the rate of dissolution as it increases the surface area available for interaction between the solute and the solvent. This allows for more solute-solvent interactions to occur simultaneously, speeding up the dissolution process.
Which best describes the economic effect that results when the government increases interest rates?
Borrowing money becomes more expensive and there is less investment in production.
What effect does exercise have on your appetite?
