Mike takes his temperature with a thermometer three times over a 20 minute period and observes the following measurements: 98, 106, and 89 degrees. In this context, Mike concludes that the of the thermometer is .

Available options are;

A. validity; high

B. variability; low

C. reliability; low

D. reactivity; high

Answer is C. reliability; low

Explanation:

Normal body temperature is considered to be 37°C (98.6°F); however, a wide variation is seen. Among normal individuals, mean daily temperature can differ by 0.5°C (0.9°F), and daily variations can be as much as 0.25 to 0.5°C. So we can see that the 98 to 106 to 89 degrees shows that the thermometer is not reliable.

Option C==> reliability; low.

Explanation:

Thermometers are instruments used in the measurement of temperature and there are various types of thermometers. Although, this does not happen all the time but sometimes when thermometers are not in good condition they give results that are not reliable such as the result Mike got in the question above. The body temperature of humans is 37°C when the person is in good condition and it may read 38°C or 39°C when someone not feeling okay and this is the number one thing that makes the thermometer unreliable.

The second is because the results of the temperature are not even precise.
