If someone measured a height to have a standard deviation of 1ft, explain why it would be necessary and important to know if you were measuring a person or a building. Which would have more error? Does the standard deviation alone tell you how accurate you are?

Answer #1

Standard diviation tells us that how the measurements are spread out from the avarage or expected value.

It is necessary to know whether the standard diviation is for a measurement of a person or building because if it were a person , the measurements are diviated on a rate of 1 feet than the expected value.So for human scale,it shows a high percentage of error.

If it were measurement of a building, a 1 feet diviation is acceptable and doesnot account for much error.

No, standard diviation much more gives us information about precision of the measurements.

Male heights have a mean of 70 inches and a standard deviation of 3 inches. Thus, a man who is 73 inches tall has a standardized score of 1. Female heights have a mean of 65 inches and a standard deviation of 2 ½ inches. These measurements follow, at least approximately, a bell-shaped curve. What do you think this means? Explain in your own words. What is the standardized score corresponding to your own height? Does this value show that...
