Question
1. What scale of measurement in the DV?
2. If you were going to create a cumulative relative frequency polygon, what would be the first and last data points used on the x-axis?
3.if you create a frequency polygon, what will be the first and last data points used on your x axis?
4. You hypothesized that most of the anxiety levels would be below 19. Does it appear that the hypothesis is correct?
5.You are one of the researchers on a research project that addresses adult stress and anxiety. You are specifically interested in gender differences in anxiety related to the predicted zombie apocalypse. Therefore, you administer the Manifest Anxiety Scale (MAS) to 30 males and 30 females at a local university after a video about zombies. A MAS score of "0" represents a normal anxiety level. Here are the MAS scores:
47 49 44 29 35 39 21 15 10 11 40 10
32 21 43 19 40 42 47 34 18 23 46 19
15 38 41 21 45 10 47 38 8 16 41 15
25 47 12 17 49 27 12 41 16 37 24 23
15 49 31 25 47 39 30 44 9 30 24 9
What is the dependent variable in this study?
Explanation / Answer
Answer:
1. What scale of measurement in the DV?
Ratio scale
2. If you were going to create a cumulative relative frequency polygon, what would be the first and last data points used on the x-axis?
First data point is mid point of first class interval and last point is the mid point of last class interval.
3.if you create a frequency polygon, what will be the first and last data points used on your x axis?
First data point is 0 and last point is 0 ( after connecting the mid points of the class intervals, we are connecting the line to the x axis)
4. You hypothesized that most of the anxiety levels would be below 19. Does it appear that the hypothesis is correct?
No, most of the values above 19.

What is the dependent variable in this study?
Dependent variable is MAS score.
