Question

8 multiple choice 10 points which of the following scales of measurement is used for a frequency - distribution polygon? nominal scales ordinal scales interval or ratio scales all of the above 9 true or false 10 points in a distribution with a positive skew, the scores with the highest frequencies are located on the right side of the distribution. true false 10 true or false 10 points in a symmetrical distribution, it is possible to draw a vertical line through the middle so that one side of the distribution is a mirror image of the other. true false

Explanation:

• For question 8: Interval or ratio scales are used for frequency - distribution polygons as they provide numerical values that can be plotted on a graph. Nominal and ordinal scales are qualitative or rank - based and not suitable for the continuous nature of a frequency - distribution polygon.
• For question 9: In a positively skewed distribution, the scores with the highest frequencies are located on the left side of the distribution, not the right. The tail of the distribution extends to the right.
• For question 10: By definition, in a symmetrical distribution, a vertical line can be drawn through the middle such that one side is a mirror image of the other.

Answer:

1. Interval or ratio scales
2. False
3. True
