accuracy, precision, repeatability, reproducibility, and validi

Which term matches the following definition?
Definition: When an experiment investigates what it sets out and/or claims to investigate. Both experimental design and the implementation should be considered when evaluating. If the investigation is flawed and controlled variables have been allowed to change then it is not this.

Which term matches the following definition?
Definition: When a measurement value is judged to be close to the true value of the quantity being measured.

• Validity

• Accuracy

• Precision

Which term matches the following definition?
Definition: How close two or more measurements are to each other. Gives no indication of how close the measurements are to the true value.

• Validity

• Accuracy

• Precision

• Repeatability

• Reproducibility

Which term matches the following definition?
Definition: The closeness of the agreement between the results of successive measurements of the same quantity being measured, carried out under the same conditions of measurement. These conditions include the same observer, the same measurement procedure, the same measuring instrument used under the same conditions, the same location, and replicate measurements on the same or similar objects over a short period of time.

Which term matches the following definition?
Definition: The closeness of the agreement between the results of measurements of the same quantity being measured, carried out under changed conditions of measurement. These changed conditions, involving replicate measurements on the same or similar objects, include a different observer, different method of measurement, different measuring instrument, different location, different conditions of use and different time.

Finish the following paragraph by connect the analysis to the correct term.

In this case, the true concentration is 200 mg/L. The average results obtained by the students are 194 mg/L, 198 mg/L, and 197 mg/L for Students A, B, and C, respectively. These results are close to the true value but consistently underestimating it, indicating a systematic error that might be due to calibration issues with the apparatus or a systematic procedural error. Thus, the experiment demonstrates moderate...
