What is correlation explain with example?
Correlation means association – more precisely it is a measure of the extent to which two variables are related. Therefore, when one variable increases as the other variable increases, or one variable decreases while the other decreases. An example of positive correlation would be height and weight.
What is a correlation give an example of one?
What is a correlation? Give an example of one. A measure of the extent to which two variables are related. An example would be height and weight.
What is correlational research and example?
A correlational research design measures a relationship between two variables without the researcher controlling either of them. It aims to find out whether there is either: Positive correlation. Both variables change in the same direction. As height increases, weight also increases.
What is the purpose of a correlational study?
The aim of correlational research is to identify variables that have some sort of relationship do the extent that a change in one creates some change in the other. This type of research is descriptive, unlike experimental research that relies entirely on scientific methodology and hypothesis.
What are the strengths and weaknesses of correlational studies?
Strengths and weaknesses of correlation
| Strengths: | Weaknesses |
|---|---|
| Calculating the strength of a relationship between variables. | Cannot assume cause and effect, strong correlation between variables may be misleading. |
What correlation means?
“Correlation” is a statistical term describing the degree to which two variables move in coordination with one-another. If the two variables move in the same direction, then those variables are said to have a positive correlation. If they move in opposite directions, then they have a negative correlation.
What is the primary weakness of a correlational study?
A weakness of correlational studies is that they can harbor biases due to self-selection into groups being compared. Correlational studies can be costly, but often they are not. They are less artificial than studies involving interventions, and are often reasonably practical and manageable to implement.
What is the major limitation of the correlational method?
An important limitation of correlational research designs is that they cannot be used to draw conclusions about the causal relationships among the measured variables. Consider, for instance, a researcher who has hypothesized that viewing violent behavior will cause increased aggressive play in children.
What is the primary weakness of this passage both Nathaniel?
Explanation: The key weakness of the given passage is that ‘it fails to establish a debatable claim.
What is one disadvantage of the experimental method?
What are the 2 major disadvantages of the experimental method? Experiments are often artificial and doubts arise about the applicability of the findings.
What are the merits and demerits of experimental method?
Advantages and Disadvantages of Experimental Research: Quick Reference List
| Advantages | Disadvantages |
|---|---|
| researcher can have control over variables | can produce artificial results |
| humans perform experiments anyway | results may only apply to one situation and may be difficult to replicate |
What are the strengths and weaknesses of experimental design?
Strengths and weaknesses of experimental methods
| Strengths: | Weaknesses: |
|---|---|
| Tighter control of variables. Easier to comment on cause and effect. | Demand characteristics – participants aware of experiment, may change behaviour. |
| Relatively easy to replicate. | Artificial environment – low realism. |
What are the strengths and weaknesses of a survey?
Key Takeaways. Strengths of survey research include its cost effectiveness, generalizability, reliability, and versatility. Weaknesses of survey research include inflexibility and issues with depth.
What are weaknesses in experiments?
Weaknesses: The main weakness of the experimental method is their dependence on what many see as an “artificial” environment. Experimental methods require the researcher to identify and control all relevant variables that might distort the apparent relation between independent and dependent variables.
What are the strengths of quantitative?
Quantitative method
| Strengths | Limitations |
|---|---|
| Relatively easy to analyse | Difficult to understand context of a phenomenon |
| Data can be very consistent, precise and reliable | Data may not be robust enough to explain complex issues |
How do you report quantitative data?
Quantitative studies
- Demographic data that describe the sample are usually presented first.
- Remind the reader of the research question being addressed, or the hypothesis being tested.
- State which differences are significant.
- Highlight the important trends and differences/comparisons.
