What is t?

What is r2?

n = 25
MD 4.7
s2 = 64

To answer your question about "t" and "r2," I would need more context or information about what you specifically mean by those terms. "t" and "r2" can represent different things depending on the context. In statistics, "t" typically refers to the t-distribution or the t-test, while "r2" usually refers to the coefficient of determination in regression analysis.

For the given information you provided:
- "n = 25" represents the sample size, which indicates the number of observations or data points in your dataset.
- "MD = 4.7" likely represents the mean deviation or the difference between the mean of the dataset and a specified value (e.g., population mean, hypothesized mean).
- "s2 = 64" represents the variance, which measures the spread or dispersion of the dataset.

It's important to note that without further context and more details, it is difficult to provide a precise answer. If you can provide more clarity regarding your question or definitions of "t" and "r2" in your specific context, I would be happy to assist you further.
