What is an controlled experiment?
A controlled experiment can be used to test almost anything. In a controlled experiment, the scientist (or experimenter) use a control group and an experimental group. The control group has nothing changed about it, and experiment group is changed based on the variable of the experiment. One of the most common uses of controlled experiments is the testing of new medications. In a medical study, a pharmaceutical company usually brings in a group of 100 people. Those people people are randomly assigned to two groups of 50. The experiment group is given the medication being tested, and the control group is given a placebo (a sugar pill). After several weeks, the experimenter can then see the side-effects of the medication, by comparing the differences between the experiment and control groups.
Why are the new medicines tested?
new medicines are tested to ensure that they work on the right aspect of what they are made for and to see if any side-effects can be harmful or worse, fatal, to human beings.
A new concept that is tested in a scientific investigation is known as?
hypothesisa hypothesis
What is the purpose of control in a experiment?
A control experiment is a very important aspect of the scientific method.Control experiments are used to minimize influences such as bias, genetic and biological variations, environmental changes, and random skewing.In a controlled experiment one set of samples have been (or is believed to be) modified and the other set of samples are either expected to show no change (negative control) or expected to show a definite change (positive control).Control experiments are especially useful in testing the effectiveness of new pharmaceuticals.For example:Let's say a company is developing an anti-smoking aid - which we'll call 'Cigstop' - and it has reached the human testing stage. To judge the effectiveness of the drug a control experiment would be administered to two groups.The first group would receive Cigstop in its prescribed format, while the second group (the control) would receive a placebo believing it to be Cigstop.Both groups are then instructed to attempt to quit smoking over a set period of time.Once the experiment has concluded one can compare the two groups and determine the success rate of the drug. If the group that actually received Cigstop had a higher percentage of quitters than the control, then the drug shows an ability to assist someone in quitting smoking. Multiple control experiments showing the same results would verify the statistical probability of the drugs effectiveness.Experiments such as the one above conducted without a control group could lead to unverified claims, and may be regarded as psuedo-science.
What are the components needed in order for an experiment to be valid Identify these components in the following experiment A scientist is testing a new plant food to see if it causes plants to grow?
Peer review does the same thing for science that the "inspected by #7" sticker does for your t-shirt: provides assurance that someone who knows what they're doing has double-checked it. In science, peer review typically works something like this:

How long does it takes for the average new drug to be tested and approved for sale in the United states?
It takes about 10 to 15 years for a new drug to be tested and approved for sale in the United States.
How long does it take for a new drug to be tested and approved?
It can easily take 10 years or more for a pharmaceutical company to get their drug from the test phase to when it is approved for human consumption by the FDA.
Can you demand a new drug test if your employer says you tested positive?
You can. Your employer can demand you pay for it.
Single blind experiment?
In a double-blind experiment, neither the researchers or the human test subjects know if they are receiving the tested medication or just a placebo (a harmless substance). This eliminates any bias by either the subject (who may psychologically influence his condition) or the experimenter (who may otherwise see effects that are not due to the treatment). While there are logistical and ethical questions that make double-blind experiments difficult, the ultimate aim is to definitively establish whether a drug or treatment actually works.
Does souplantation drug test their new employees If so what type?
As a current employee, they do not drug test. In the employee manual , it states that basically if you come to work High, then they will drug test you, but other than that I haven't been drug tested, I've worked here for over 3 months and a coworker for 3 years and not once drug tested him.
