When your experimenter results are not what you predicted what should you do?

Double-check your procedure and your lab technique. If they're still not what you predicted after eliminating any potential sources of error, then evidently you've learned that your initial premises were wrong, and you'll have to reject your hypothesis since you've proven that it's false.

Why are predicted ratios rarely the same as actual ratios?
They Are Rarely The Same Because With Predicted Ratios Its Just A Guess But With A Actual Ratio You Have Accurate Answers .
How long does it take to get bone scan results?
It should usually take about 24 hours.
Which condition is necessary for an experiment to yield useful data?
similar results should be obtained when the experiment is repeated .
How did the results of Beadle and Tatum's experiment support their hypothesis?
As Beadle and Tatum had predicted, they were able to create single gene mutations that incapacitated specific enzymes, so that the molds with these mutations required an external supply of the substance that the enzyme normally produced, and the substance that the enzyme normally used, piled up in the cell. These results led them to the one gene/one enzyme hypothesis, which states that each gene is responsible for directing the building of a single, specific enzyme.
What term is used to describe the process of monitoring operating results and comparing actual results with the expected results?
Controlling
Why should an experimenter do after analyzing test results?
Form a hypothesis.
What is experimental bias?
Experimenter Bias, also known as Experimenter Expectancy, is made up of all the things an experimenter might unwittingly do to influence the results of an experiment to resemble his hypothesis. You could consider this a self-fulfilling prophecy to some extent.
What should an experimenter do after analyzing data?
scientist analyes their experiment
What are unintended consequences?
Results of an action that were not predicted or planned
Mendel used more than 28000 pea plants in his experiment. How does this large sample size make his results more reliable?
it made his actual results approach the results predicted by probability
Why might a double-blind study yield more reliable results than a single-blind study?
In single blind studies, the experimenter (or observer) is aware of who or what belongs to the control group and the experimental group.In double blind studies, the experimenter is not aware of who/what belongs to which group. This is to eliminate the subjective bias an experimenter may have.
How does a large sample size help to ensure that experimental results are reliable?
It made his actual results approach the results predicted by probability
How did Mendel's large sample size make his results more reliable?
it made his actual results approach the results predicted by probability.
Why is it necessary to have an independent variable that is changed by the experimenter during an experiment?
The independent variable is changed by the experimenter so that the results can be compared to the control, which does not change. Any differences between the control and experimental group are due to the independent variable. cw: As written, you don't.
When did Electrical Experimenter end?
Electrical Experimenter ended in 1931.
When was Electrical Experimenter created?
Electrical Experimenter was created in 1913.
What are the steps when doing experimental research?
Form a hypothesisDetermine what variables can be varied that should or should not influence results when varied if the hypothesis is correct and if it is incorrectdesign experiments where those variables can be controlled for, and the results measureddetermine the a statistically valid method for running the experiments while controlling for different variablesrun the experiments, recording the resulting measurements and observationsanalyze the results and compare to the results predicted by the theory.
