[rSpqUemEta] Precision: 3 You cannot know 'without a doubt' without performing statistical analysis on these data, but the values are close together, so some level of precision is present. , Most likely YES, they are all close together YES, without a doubt & Most likely NO, they are not the same = Not sure, without a statistical test, there is no way to know You cannot know 'without a doubt' without performing statistical analysis on these data, but the values are close together, so some level of precision is present. v For the data values 15.27 inches, 15.26 inches, 15.28 inches, and 15.26 inches: Do these values appear to be precise? [rSpqUemEta] Accuracy: 5 You cannot know 'without a doubt' without performing statistical analysis on these data, but the values are not vary close to the known length, so assuming 'most likely NO' is the best option. 6 Most likely NO, this is not near the measured values. B Most likely YES, the numbers appear somewhat close to the average. NO, absolutely not. YES, without a doubt. You cannot know 'without a doubt' without performing statistical analysis on these data, but the values are not vary close to the known length, so assuming 'most likely NO' is the best option.
