What measures the strength of the linear relationship between two quantitative variables?
The coefficient of determination, otherwise known as the r^2 value, measures the strength of the linear relationship between two quantitative variables. An r^2 value of 1 indicates a complete linear relationship while a value of 0 means there is no relationship.
Are data at the nominal level of measurement qualitative or quantitative?
This kind of data is qualitative, meaning it is an observation of a particular facet of the observed thing. Quantitative date is numerically-based.

Quantitative variables use which two levels of measurement?
Interval and ratio
A graphical presentation of the relationship between two quantitative variables is?

Does qualitative research not control variables?
In qualitative research, researchers do not typically control variables in the same way as in quantitative research. Instead, they aim to explore and understand the complexities and nuances of a phenomenon without manipulating variables. The focus is on gaining in-depth insights and understanding the context in which the research is conducted.
What data can be referred to things that can be counted?
A quantitative variable is numeric and therefore can be counted discretely or continuously. The other side of the spectrum is qualitative variables.
What is the meaning of declare value?
When forming a hypothesis for quantitative research, a declarative hypothesis states the expected relation between variables, whereas a null hypothesis states that there is no significant relation.
Is anova qualitative or quantitative?
! ANOVA is generally computed for two or more QUANTITATIVE variables. If the quantitative variables are two or less in number, people prefer the t test (one sample t, paired t, or independent samples t) The Independent variable however is qualitative( for example, Girls and boys or Names of Schools.) It is the dependent variable that is Quantitative (for example, the ages - 2, 5 , 70, etc or weight or number of somethings). If you have 2 independent variables, you go for the two way ANOVA. Else, it's the one way ANOVA. !
Does quantitative research typically use independent and dependent variables?
Some times. At other times it uses mutually dependent variables (changes in each variable affect the other).
What does data mean in an experiment?
