Would love some help pleaseee. and please at least read the question instead of skipping it please. Test the Hypothesis
The next step in designing the experiment is to test the hypothesis. Experiments usually involve several that must be identified and analyzed.
• Independent variables are variables that scientists to test the effects on the dependent variables. Ideally, there’s only one independent variable.
• Dependent variables are variables by the changes made to the independent variable.
When conducting studies in medical research, some factors can’t be controlled because of time, cost, or considerations.
Repeat or Retest
Repeating a trial reduces the possibility of . Experiments should be repeated by other scientists to check for accuracy.
scientific theory – an of why a natural phenomenon occurs that is well- supported by repeated experimentation over time
 For example, the explanation of gravity happens.
scientific law – a scientifically acknowledged confirmed by repeated
experimental observations
 For example, the explanation of gravity affects objects.
Scientists create further hypotheses, analyze the data, and establish conclusions. The conclusions drawn should answer these questions:
• What happened in the experiment? •
• What are the recommendations for future research?
Communicate the Results
Scientists communicate their results to other scientists to encourage them to or the experiment. Researchers often communicate their results in scientific journals.
Thinking Scientifically
Skepticism means the truth of a claim or a fact and accepting statements as facts only when well-substantiated supports them. Being skeptical helps scientists analyze more information, observe minute details in their theories, find flaws in their designs and results, and reduce bias.
Critical Thinking
Critical thinking helps scientists work on flaws, design new studies, and find to real- life problems.
Taking Accurate Measurements
Scientists strive for measurements that are both reliable and accurate.
Reliability (consistency): The tools used to gather data give consistent results they are used.
Validity (accuracy): A piece of equipment or a test precisely measures what it is to measure.
 For example, a malfunctioning blood pressure cuff gives consistent readings that are 10 points higher than the actual reading.
The cuff is A) reliable B) not reliable and c) valid D) not valid.
