Love it. Can't live without this as people need to make forms fillable. Why scrawl out hundreds of lines in pen when I can type them beautifully?

### What is comparison method?

### What is a comparison study design?

Comparative study looks at two or more similar groups, individuals, or conditions by comparing them.

### How do you compare scores between two tests?

Test equating is the process used to establish a mathematical relationship between two scales so that the scores on these scales are based on the same metric and thus are comparable [1]. In lay terms, equating consists of establishing equivalence scores on two different scales that measure the same construct.

### How do you compare two mean values?

Independent Samples T-Test. One sample T-Test. Paired Samples T-Test. One way Analysis of Variance (ANOVA).

### How do you determine if two sets of data are statistically similar?

A t-test tells you whether the difference between two sample means is "statistically significant" - not whether the two means are statistically different. A t-score with a p-value larger than 0.05 just states that the difference found is not "statistically significant".
