What are the steps to Scientific Inquiry?
Scientific Inquiry is the ongoing process of discovery in Science. There are 8 steps to Scientific Inquiry.Observations - An observation is the process of using one or more of your sences to gather information. There are 2 types of observations. Qualitative observations and quantitative observations. A qualitative obervation is an observation that deals with characteristics that cannot be expressed in numbers. A quantitative is an observation that deals with a number, size, or amount and have a unit.Investigative Question (Scientific Question) - Pose a question for your observation.Hypothesis - a hypothesis is a possible explanation for a set of observations or answer to a scientific question that is testable. A hypothesis must be testable. This means scientists must be able to carry out investigations and gather evidence that will either support or disapprove a hypothesis.Organize experiment - create your experiment to test your hypothesis. Identify the Manipulated, Responding, and Controlled variables. Also make sure you have atleast 1 Operational Definition.Test your experiment - test your experiment to see if your hypothesis is true.Collect Data - Now you see what happens. Make a table or graph to record the data collected. Analyze the data after they have been collected.Conclusion - Consider if there are enough data to support or dis approve the hypothesis. It is also a summary of what you have learned from the experiment.Communicate - Share your ideas and experimental findings wiht others through writing or speaking.
What is the hypothesis of the given statement if pigs had wings you could fly?
You cannot fly.
When you reject the Null Hypothesis that means that the Null Hypothesis cannot be correct?
No. Rejecting the Null Hypothesis means that there is a high degree of probability that it is not correct. This degree of probability is the critical level that you choose for the test statistic. However, there is still a small probability that the null hypothesis was correct.
What is composite hypothesis?
A hypothesis which is not simple (i.e. in which not all of the parameters are specified) is called a composite hypothesis.For instance, if we hypothesize that (and) or and, the hypothesis becomes a composite hypothesis because we cannot know the exact distribution of the population in either case. Obviously, the parameters and have more than one value and no specified values are being assigned. The general form of a composite hypothesis is or, that is the parameter does not exceed or does not fall short of a specified value. The concept of simple and composite hypotheses applies to both null hypothesis and alternative hypothesis.
What is information from an experiment such as observations or behaviors that cannot be recorded with a numerical value.?
Qualitative Data
How can a scientist test a hypothesis if she or cannot do a controlled experiment?
scientists test their hypothesis buy making observations or doing research
How can a scientist test a hypothesis if its impossible to control the experiment?
To answer a specific question, scientist form a hypothesis. If the hypothesis cannot be testable or answered, they'll give you a prediction of what will most likely happen from the results of the hypothesis.
How does a scientist explain something when a controlled experiment when a controlled experiment cannot be carried out?
'm not sure what your asking but I will attempt to explain what I believe you are saying... If event "x" happens and the data is recorded... By making assumptions based on facts that are known a person can conclude "y" hypothesis is the cause, however if no experiment can be done to test this or if the experiment cannot take into account extraneous and confounding variables, then the hypothesis is unable to be tested and remains an "educated guess"... There are ways around this however... Large diverse sample sizes eliminate the possibility that it is just some random occurrence brought by something else for example..
What is the difference between a controlled experiment and a controlled group?
a controlled group is like an idea but an experiment that is controlled cannot be changed.
How scientist try to answer questions that cannot be tested with experiments?
To answer a specific question, scientist form a hypothesis. If the hypothesis cannot be testable or answered, they'll give you a prediction of what will most likely happen from the results of the hypothesis.
Tested factor in an experiment that might affect the outcome?
Many times these are things that cannot be controlled. Some factors may be temperature, time of day, and the materials that are used.
A scientist on television states that a hypothesis cannot be proven Access why this statement is correct?
When a hypothesis is proven, it is no longer a hypothesis; a proven hypothesis is a theory.
What is the variable that cannot be controlled in an experiment?
The dependent variable.
Why can a supported hypothesis not be called a theory?
A hypothesis cannot be call a theory because,it has not supported a prediction even in the face of several experiment.
Can a controlled variable be changed during an experiment?
No it cannot be changed in an expirement
Why is the hypothesis black cats cause bad luck not science?
The results of studying the hypothesis are not repeatable and are open to judgement. The hypothesis cannot be tested by controlled experiments.
