Question

Every morning, my bathroom scale tells me that I weigh 120 pounds. However, when I go to the doctor, their very accurate professional scale says I weigh 130 pounds. My bathroom scale has __________ and __________.

Answer 1

high reliability; low validity

Step-by-step explanation:

THE RELIABILITY of a measuring instrument refers to the degree of precision or accuracy of the measurement, in the sense that if we repeatedly apply the instrument to the same subject or object it produces the same results. VALIDITY refers to the degree to which an instrument measures the variable it intends to measure.
