What is the connection between hypotheses and the tests that are conducted in an investigation?
They are part of the scientific method. The test results confirm or disprove the hypothesis.
How does the lack of a normal distribution influence the analytical options available to a researcher?
Most parametric and many non-parametric tests for testing the significance of hypotheses are based on the assumption of normality - or approximate normality.
What is the relationship between logic and science?
Science is about our understanding of things. We have hypotheses about the way in which something works. We use logic to work out the consequences of the theory and then design tests to check whether or not the consequences follow. If they do then there is greater evidence in support of the theory and if not, the theory needs amending or scrapping. What distinguishes science from quackery are these logical tests, and the acceptance (sometimes reluctant) that existing theories are just plain wrong and new ones are required.
Differences between descriptive and inferential statistics?
All statistical tests are part of Inferential analysis; there are no tests conducted in Descriptive analysis · Descriptive analysis- describes the sample's characteristics using… o Metric- ex. sample mean, standard deviation or variance o Non-metric variables- ex. median, mode, frequencies & elaborate on zero-order relationships o Use Excel to help determine these sample characteristics · Inferential Analysis- draws conclusions about population o Types of errors o Issues related to null and alternate hypotheses o Steps in the Hypothesis Testing Procedure o Specific statistical tests

What is the difference between an experiment and investigation?
An experiment tests a hypothesis; an investigation mainly collects data.
What do most experiments tests?
predictions based on hypotheses
What is the difference between investigation experiment demonstration and discrepant event?
an experiment tests an hypothesis while an investigation is collecting data
How are hypotheses related to theories?
Because they are later answered by real tests
In order to arrive to a solution a problem a scientist usually propses and tests?
Hypotheses
How is science used in psychology?
Psychology creates and tests hypotheses like any other type of science.
When applying the process of science which one is tested?
When applying the process of science, hypotheses are tested. Hypotheses are educated guesses about the relationship between variables and are used to make predictions that can be tested through experimentation or observation. The results of these tests help to determine whether the hypothesis is supported or rejected.
What word belongs to this definition an investigation that tests only one factor at a time?
a controlled experiment
What is a routine laboratory investigation?
A routine laboratory investigation is a series of standardized tests conducted on bodily fluids, tissues, or other samples to assess a person's health status. These tests typically include blood tests, urine analysis, and other common diagnostic procedures to screen for various health conditions or monitor treatment effectiveness.
What do scientists perform after making a hypotheses?
They set out to test a hypothesis by using experiments and controls. They then adjust the experiments and run the tests again until they either prove or disprove it.
