Question
1) Suppose you want to weigh yourself. Before stepping on the scale, you pick up a 5 lb dumbbell and record your weight while holding it. You repeat this several times and use the average of the several measurements as your final estimate of your weight. What does the dumbbell add to the final estimate?
Bias
Chance error
An outlier
All of the above
None of the above

Explanation / Answer
Here we want to measure the weight of an individual . Given that Before stepping on the scale, you pick up a 5 lb dumbbell and record his weight while holding it.
we repeat this procedure several times and use the average of the several measurements as your final estimate of your weight.
Here due to this procedure we doesnot get reliable results
Due to this inaccurate procedure some bias is produced and which influenced on our results.
bias would be the tendency of a sample statistic to systematically over- or under-estimate a population parameter.
OPTION A ) BIAS IS CORRECT
Q 2 ) Suppose you want to weigh yourself.
Before stepping on the scale, you pick up a 5 lb dumbbell and record your weight while holding it.
You repeat this several times, and each time the measurement is a little different.
So the reason for these differences in the measurements is due to CHANCE ERROR
It is defined as the difference between the predicted value of a variableand the actual value of the variable.
OPTION B) CHANCE ERROR IS CORRECT
