What is experimental correlation and natural correlation?
the correlations we observe in the world around us
Which one of the following method serve to measure correlation bw two variable?
cofficient of rank correlation
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
Spearman-Brown formula ptherwise called as split half method?
not otherwise....split half method is one way of determining reliability of your test and Spearman-Brown formula is a technique used to re-calculate the correlation of your test when you split your test items into half.... this means that the result of Spearman-Brown provides you the correlation of your test in full length.
What is a sample correlation?
If measurements are taken for two (or more) variable for a sample , then the correlation between the variables are the sample correlation. If the sample is representative then the sample correlation will be a good estimate of the true population correlation.
What is experimental correlation and natural correlation?
the correlations we observe in the world around us
Which one of the following method serve to measure correlation bw two variable?
cofficient of rank correlation
What distinguishes Isaac Newton from others physicist?
Isaac Newton understood mathematics , theoretical physics and experimental physics.
Which data collection method is not subject to non response bias?
experimental method
What analysis methods cannot be applied to experimental research?
which analysis method cannot be applied to experimental research
A Research method that can establish a causal link is?
experimental
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 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
Why is the correlational method even considered if the experimental method is the only research method that identifies cause and effect?
While the experimental method is ideal for determining cause and effect, the correlational method is still valuable for studying relationships between variables when it's not feasible or ethical to manipulate them. Correlational studies can provide useful information about associations between variables and generate hypotheses for further experimental research.
What are difference between correlation method and experimental method?
The correlation method examines the relationship between two variables without manipulating them, while the experimental method involves manipulating one variable to observe its effect on another. Correlation does not imply causation, whereas experimental research can establish cause-and-effect relationships. Experimental research allows for greater control over variables compared to correlational studies, making it better suited for establishing causality.
What research method yields the most definite evidence of cause effect conclusions?
Experimental research method yields the most definite evidence of cause-effect conclusions because it involves manipulating variables, controlling extraneous factors, and randomly assigning participants to conditions, allowing researchers to establish a causal relationship between variables.
