What are unexpected results in research?
● An unexpected result is one that runs counter to what prior evidence or informed hypotheses would suggest. This could mean an evaluation that shows no evidence of impact (null), a smaller or larger impact than prior evidence would suggest, or one that points to inconsistent program implementation.
When a scientist gets an unexpected result in an experiment What should they do?
Answer: If a scientist gets unexpected results from her experiments, she should carry out the same for some more time so that the unexpected inference can be confirmed and a sure conclusion can be reached.
What can affect results in an experiment?
Variables such as temperature, humidity, pressure, gravity, elevation, vibration, stress, strain, lighting, etc. can impact the measurement result. Some tests and calibrations are more sensitive to certain environmental factors than others.
What is a common cause of bad results in an experiment?
The two main reasons that your results might not match up each time are uncontrolled conditions and experimental error. Uncontrolled conditions will likely influence your results because you haven’t controlled for all of the variables that affect your experiment.
What is an unexpected outcome?
If an event or someone’s behaviour is unexpected, it surprises you because you did not think that it was likely to happen.
What happens when a scientists expectations change how the results of an experiment are viewed?
A bias occurs in an experiment when a scientist expects something to happen and lets this influence how the results are viewed. Scientists try to reduce bias whenever they can by doing the experiment many times and keeping careful notes about observations.
What is one way early scientific practice?
Answer Expert Verified. Early scientific practices differed from modern scientific practice by – Early hypotheses were not tested by experimentation. Since the 17th century, scientific methods included systematic observation, measurement, formulation, experiment, testing, and modification of hypotheses.
What makes an experiment valid?
Four basic components that affect the validity of an experiment are the control, independent and dependent variables, and constants. These basic requirements need to be present and identified to consider an experiment valid.
What makes an experiment accurate?
When a scientist repeats an experiment with a different group of people or a different batch of the same chemicals and gets very similar results then those results are said to be reliable. Reliability is measured by a percentage – if you get exactly the same results every time then they are 100% reliable.
How do you explain inconsistent findings?
Several findings for different nodes can be inconsistent with each other. This is the most common form of inconsistency. When Netica alerts you that findings are inconsistent, then it means that according to this Bayes net, it is impossible to observe the set of findings you have entered.
What types of errors can occur in an experiment?
There are two types of errors: random and systematic. Random error occurs due to chance. There is always some variability when a measurement is made. Random error may be caused by slight fluctuations in an instrument, the environment, or the way a measurement is read, that do not cause the same error every time.
