Answer :
Final answer:
The thermometer you used showed reliability as the readings were consistent, however, it lacked validity as it doesn't measure the body temperature correctly compared to the hospital-grade thermometer. An accurate thermometer is necessary to measure this vital sign and thermometers are usually calibrated to the temperature scales like Fahrenheit and Celsius to give accurate readings.
Explanation:
The measurements that you've collected from your quick scan thermometer exhibit reliability because they've consistently given the same reading. However, based on the comparison to the accurate reading from the hospital grade thermometer, it appears that there is a lack of validity. Validity refers to how well a tool measures what it is supposed to measure. In this case, the thermometer ought to accurately measure your son's body temperature, but it seems it has consistently overestimated it by 0.9 degrees Fahrenheit, compared to the hospital grade thermometer.
Disease signs such as body temperature can be used to assess health, and an accurate thermometer is essential to measure this vital sign. Normal body temperature is generally accepted as 98.6°F, but can be influenced by various factors like physical activity, eating, and time of day.
Temperature scales like Fahrenheit and Celsius comprise of an interval scale where temperature measurements are relative to a reference point (freezing point of water for Celsius and lower bound of Dr. Fahrenheit's scale for Fahrenheit). Thermometers are calibrated to these scales to give an accurate measurement.
