What method allows researchers to observe the variable of interest without interference from other variables?

Researchers engaged in naturalistic observation usually make their observations as unobtrusively as possible so that participants are not aware that they are being studied. Such an approach is called disguised naturalistic observation.

What is the correct term for a pattern of variation that is noted in a given data set?

Variability (also called spread or dispersion) refers to how spread out a set of data is. Variability gives you a way to describe how much data sets vary and allows you to use statistics to compare your data to other sets of data. The four main ways to describe variability in a data set are: range.

How variable is handled or manipulated in correlational research?

Data Collection in Correlational Research Again, the defining feature of correlational research is that neither variable is manipulated. It does not matter how or where the variables are measured.

How do you determine variability?

Measures of Variability: Variance

1. Find the mean of the data set.
2. Subtract the mean from each value in the data set.
3. Now square each of the values so that you now have all positive values.
4. Finally, divide the sum of the squares by the total number of values in the set to find the variance.

What is pattern of variation?

A bimodal distribution signals that the process has a special cause of variation present. Something has changed in the process. There are operating differences between shifts, changes in processing methods, temperature and humidity differences, equipment differences, raw material changes, or other differences.
