Use the appropriate alphabet (a, b, c, d, etc.) to indicate your answer for each Multiple Choices. Circle the most appropriate answer A. This scale of Measurement is categorical data that indicate differences in magnitude. The Scale is most likely 1. Ratio 2. Interval 3. Nominal 4. ordinal 5. Either 3 or 4. B. A measurement performed in triplets where the values are approximately the same 1. Accurate 2. Accurate and Precise 3. Precise 4. Accurate but not precise 5. Precise but not accurate C The statistical population is Howard University. Mary and Susan are members of the senior class. Based upon what is known, they are 1. An observation 2. Random observations 3. A Sample 4. A random sample 5. Both 2, 4. D. The Normal Curve is described as being 1. Leptokurtic 2. Platykurtic 3. Mesokurtic 4. Uniform 5. Both 3, 4Explanation / Answer
A ) 2.Interval
When a variable is measured on an interval scale, the distance between numbers or units on the scale is equal over all levels of the scale. An example of an Interval scale is the Farenheit scale of temperature. In the Farenheit temperature scale, the distance between 20 degrees and 40 degrees is the same as the distance between 75 degrees and 95 degrees.
B) 3.Precise
Precision refers to the closeness of two or more measurements to each other. Using the example above, if you weigh a given substance five times, and get 3.2 kg each time, then your measurement is very precise. Precision is independent of accuracy. You can be very precise but inaccurate, as described above. You can also be accurate but imprecise.
C) 4.Random sample
D) 3. Mesokurtic -
A term used in a statistical context where the kurtosis of a distribution is similar, or identical, to the kurtosis of a normally distributed data set. Kurtosis is a measure of a distribution's peak, which means how much of the distribution is centered on the distributions mean.
