Using the ouput, the researcher concludes that the true population mean is likely between 1.394 and 6.606 (knowing that the estimate could be incorrect).
Confidence intervals provide a range estimate for a population value (e.g., the mean). Note that the width of the interval can be altered to reflect the level of confidence in the estimate.
The participants (N = 8) scored low on the Outcome (M = 4.00, SD = 3.12), 95% CI [1.39, 6.61].
