What is power function in statistics?
In statistics, we have to test the hypothesis i.e., null hypothesis and alternative hypothesis. In testing, most of the time we reject the null hypothesis, then using this power function result, then tell what is the probability to reject null hypothesis...
Do you already know the correct answer to a hypothesis before you being collecting data?
Typically, no. While a researcher might anticipate a particular result, the hypothesis is only that - what the expected result might be (and often, there may be several possible expected results or even none.)
How do you find the test statistic for a mean hypothesis test?
You can calculate a result that is somehow related to the mean, based on the data available. Provided that you can work out its distribution under the null hypothesis against appropriate alternatives, you have a test statistic.
How is a conclusion different from data analysis?
The basic difference between a data analysis and a conclusion is that, a data analysis deals with the information and or data you have obtained from doing a certain experiment. it also deals with organizing and examining the collected data using narratives, charts, graphs or tables and analyzing( or interpreting) the information you have. Whereas, the conclusion literally means the answer to the experiment. the conclusion explains the experiment in an overall basis and explains your hypothesis right or wrong. For example; If you want to check the affect of different lights on the growth of a certain plant, first you will make an hypothesis. Later, materials, purpose, procedures, observations, data/graphs......At the end you will have to do your conclusion. In your conclusion you will explain, if the light did have an affect on the certain plant, basically checking to see if your hypothesis was correct or incorrect. The conclusion is also known as a final settlement and it ends the experiment by showing what happened as the result?..............Hope that helped!!
How is the power of a statistical test defined?
The power of a statistical test is defined as being a probability that a test will product a result that is significantly different. It can be defined as equaling the probability of rejecting the null hypothesis.
What tests your hypothesis?
By conducting your experiment, the result of that experiment either agrees with your hypothesis or disagrees your hypothesis.
If the result from your investigation do not support your hypothesis what should you do?
Revise or discard your hypothesis.
What is Predation Coefficients?
coefficients that measure the efficiency of predation - for the prey, it is the proportion of encounters that result in the death of a prey individual; for the predator, it is the proportion of encounters that result in the death of a prey individual multiplied by the proportion of a new predator individual contributed by a prey individual.
What is result in a science project?
A result is if your hypothesis was whether right or wrong and then explain it.
What happens if the experiment dose not confirm hypothesis?
This indicates that the hypothesis is probably incorrect and a new hypothesis needs to be developed. A negative result for a scientific experiment is just as important as a positive result and means that the experiment was a success.
How does hypothesis affect a scientific investigation?
The hypothesis is an educated guess, it should not affect the investigation at all, it is merely a summized thought based on known evidence and a prediction of a possible outcome. A scientist however does not use that Hypothesis to get a result, they merely see if the result lines up with the Hypothesis. A quick example is you see a movie billboard, it has squirrels on it fighting, you can hypothesize the movie is about squirrels fighting. Now if you go see the movie and it has no squirrels at all, your hypothesis is wrong.... You can not go to the movie, see no squirrels, then squint your eyes really tight till the animals that are in the movie look like squirrels fighting, just to say your hypothesis was right. It should have no impact on the results of scientific study... it is merely an educated guess at a possible outcome of the tests.
What do you need a hypothesis for?
To predict what do you think your result will be for your experiment.
How do scientists use statistics when they test a hypothesis?
When testings a hypothesis, statistics can be used to calculate the chances or probability of getting a result

What 10 letter word states what the result of an experiment will be?
hypothesis
What can scientist do if the result of an experiment do not support a hypothesis?
draw conclusions
What is it called when a experimental result matching the prediction is called?
Hypothesis.
