An experimental study allows researchers to establish causal relationships between variables by manipulating one or more independent variables and observing the effect on a dependent variable. This control over variables enables conclusions about cause and effect that cannot be drawn from observational studies, where confounding factors may influence the results. Therefore, only from an experimental study can one confidently conclude that changes in the independent variable directly cause changes in the dependent variable.
What else can I help you with?
Why it is important that there is only one possible explanation for experimental data?
If more than one explanation is possible, a conclusion about one of them cannot be reliable
What conditions must be met if you want to have a scientifically valid sample for a study?
You must have a control group, an experimental group, an experimental variable (also called the independent variable), and a response to be measured (also called the dependent variable). The experimental variable is applied only to the experimental group, so that any difference between the control group and experimental group is due only to the experimental variable. Both the control group and experimental group must have the same conditions, except for the experimental variable.
Why do scientists write conclusions to experiments?
The conclusion is the goal of performing the experiment, without it the written results of the experiment would only be a "jumble of data". Other scientists need the conclusion both to validate the experimenter's reasoning and to decide on future experimental directions to take.
What has to be done before making a conclusion?
Before making a conclusion, it’s essential to gather and analyze relevant information and evidence. This involves critically evaluating the data, considering different perspectives, and identifying any biases or assumptions. Additionally, it’s important to ensure that the reasoning is logical and supported by the evidence collected. Only after careful consideration of these factors should a conclusion be drawn.
Is conclusion and results the same?
No it's not the same because there are many results but only 1 conclusion.
What conclusion can be drawn from the experiment when amylase and maltase were added to a maltose solution?
Maltase digests only maltose
Cause and effect conclusions can be drawn from what kind of studies?
Cause and effect conclusions can be drawn from experimental studies, where researchers manipulate an independent variable to observe its effect on a dependent variable. Correlational studies, on the other hand, can only show associations between variables but not causation.

If more than one explanation is possible, a conclusion about one of them cannot be reliable

Are the control and experimental groups are designed to be identical?
In an ideal experimental design, the control and experimental groups are designed to be as similar as possible, with the only difference being the specific treatment or intervention that the experimental group receives. This helps to isolate the effect of the treatment and minimize the impact of other variables on the outcome of the study.

What could be wrong with my lower back?
You need to consult your family physician or the general physician. He will treat you or may take the opinion of the spine specialist. Then only some conclusion can be drawn about your back.
What was the main conclusion drawn from the Hawthorne studies?
The main conclusion drawn from the Hawthorne studies was that workers' productivity is influenced not only by physical factors but also by psychological and social factors such as attention from management and group dynamics. This highlighted the importance of considering and managing these behavioral aspects in the workplace to improve productivity and job satisfaction.

What comes first recommendation and conclusion or conclusion and recommendation?
Conclusion comes first, then the evaluation.
What effect does non-random sample have on what you can say about the results of a study?
It means that the results of the study cannot be claimed to hold for the entire population from which the sample was drawn. The researchers can only claim that their results hold for the individuals selected into their sample.
Did experimental physics or the theoretical physics come first?
Experimental physics. Only with experiments come a theory:)
