What is experimental correlation and natural correlation?
the correlations we observe in the world around us
What Correlation method example?
One common example of a correlation method is Pearson's correlation coefficient, which measures the linear relationship between two continuous variables. For instance, researchers might use this method to analyze the correlation between hours studied and exam scores among students. A positive value close to +1 indicates a strong positive correlation, while a value close to -1 indicates a strong negative correlation. This method helps in understanding how changes in one variable may relate to changes in another.
Which one of the following method serve to measure correlation bw two variable?
cofficient of rank correlation
Can correlation alone prove causation?
No, correlation alone cannot prove causation. While a correlation between two variables indicates that they may be related, it does not demonstrate that one variable causes the other. Other factors, such as confounding variables or coincidence, can also explain the observed correlation. Establishing causation typically requires further evidence, such as experimental data or longitudinal studies.
What are the different ways in gathering data in statistics?
1. Direct Interview/Interviewing 2. Indirect/Questionnaire -->used in researching 3. Registration Method 4. Experimental Method

What factor distinguishes the expermental group from the control group?
The factor that distinguishes the experimental group from the control group is that the experimental group is subjected to the experimental treatment or intervention being studied, while the control group does not receive this treatment and is used as a baseline for comparison.

What distinguishes Isaac Newton from others physicist?
Isaac Newton understood mathematics , theoretical physics and experimental physics.
Which factor distinguishes the experimental group from the contol group?
The experimental group receives the intervention or treatment being studied, while the control group does not receive the intervention and is used as a baseline for comparison.
Which factor distinguishes the experimental group from the control group a conclusion a variable a hypothesis a theory?
The factor that distinguishes the experimental group from the control group is a variable. Specifically, it is the independent variable that is manipulated in the experimental group to observe its effect, while the control group remains unchanged to provide a baseline for comparison. A conclusion, hypothesis, and theory are related to the research process but do not serve this distinguishing purpose.
Which data collection method is not subject to non response bias?
experimental method
What are the advantages and disadvantages of correlation method?
The advantage of the correlational research method is the ability to prove a positive or negative correlation between two subjects . The disadvantage of this is the unclear interpreation of cause and affect. moletsane
What analysis methods cannot be applied to experimental research?
which analysis method cannot be applied to experimental research
What advantage does the experimental method have over non-experimental methods of research?
The experimental method allows researchers to establish cause-and-effect relationships by manipulating variables and controlling for confounding factors. This method provides more control over the research setting, increasing internal validity compared to non-experimental methods.
What is the research method in which the investigator manipulates a variable under carefully controlled conditions?
Experimental Method
