Can you correlate two different scales?

The value between +1 and −1 that represents the correlation between two scales is the interscale correlation. A researcher may choose to determine the interscale correlation in situations in which she/he has multiple scales and wants to investigate the relationship between the variables that those scales are measuring.

Can you correlate Likert scales?

Dear, Yes you can do correlation as Likert scale is called Summeted scale too.

Can you have a 2 point Likert scale?

The 2 points Likert scale is the simplest Likert scale question example where there’ll be just two Likert options, such as agree and disagree as two poles of the scale. It is typically used to measure Agreement.

What statistical analysis should I use for Likert scale?

For ordinal data (individual Likert-scale questions), use non-parametric tests such as Spearman’s correlation or chi-square test for independence. For interval data (overall Likert scale scores), use parametric tests such as Pearson’s r correlation or t-tests.

What is Spearman’s rank order correlation?

The Spearman rank-order correlation coefficient (Spearman’s correlation, for short) is a nonparametric measure of the strength and direction of association that exists between two variables measured on at least an ordinal scale. It is denoted by the symbol rs (or the Greek letter ρ, pronounced rho).

What does Spearman’s correlation show?

Spearman’s correlation measures the strength and direction of monotonic association between two variables. Monotonicity is “less restrictive” than that of a linear relationship. For example, the middle image above shows a relationship that is monotonic, but not linear.

Can a Likert scale be qualitative?

Likert scales are attitudinal and because of that they are qualitative in nature and as such they are non-metric so we have to use the appropriate statistical tools using nonparametrics.

Can I use Chi-Square for Likert scale?

In general, don’t use Chi-square for Likert items.
