1)
This graph is a Frequency polygon.
This type of graph is used for a variable that is measured on an interval or ratio scale.
2)
This graph is a Histogram.
This type of graph is used for a variable that is measured on an interval or ratio scale

What is the difference between a bar chart and a histogram? Why are the bars separated in the former but not in the latter? What types of variables are appropriate for each? As a class, discuss a classification scheme for deciding what type of graphic device to use for for the following types of variable: discrete, dichotomous, nominal, ordinal, interval/ratio, and continuous. Is there any additional information that would be useful to consider toward helping students to avoid confusing the...
7. Constructing histograms and polygons Aa Aa The frequency distribution table for a variable measured on a ratio scale is given here. Score f 4 8 Use a polygon to graph the frequency distribution. (Hint: You will use the points to construct your polygon, not the rectangles. The line segments automatically connect your points. Lay the points of the polygon across the bottom of the graph to start; then drag each point to its correct height. This will avoid the...
Question 8: Only an experiment can demonstrate cause-and-effect relationships between variables. Question 8 options: A) True B) False Question 9 Saved A researcher observes the number of tasks completed by male and female participants during a multitasking observation period. In this example, sex (male, female) is the quasi-independent variable. Question 9 options: A) True B) False Question 10 Children are randomly assigned to complete a low, moderate, or high difficulty task. The time (in seconds) it takes them to complete...
Question 7 Order the following levels of measurement from highest to lowest in terms of requirements. - 1. 2. 3. 4. Nominal - 1. 2. 3. 4. Ratio - 1. 2. 3. 4. Interval - 1. 2. 3. 4. Ordinal Question 8 To show changes in the rate of homicide from 1990 to the present, by year, a researcher would probably use a line chart pie chart bar graph histogram Question 9 What type of value can greatly affect a...

If a study was done that asked college students exactly how many A’s they have obtained (e.g., 0, 1, 2, etc.), the researcher is using: A nominal measure An ordinal measure An interval measure A ratio measure Provide an example of each of these two scales (ordinal and interval/ratio) that represent students’ performance in a statistics course. You found that a zero is included in a scale of a measurement. Which of the following is correct about the measurement scale?...
The Correctional facility that you work is considering using a new program designed to improve the pro-social attitudes of violent offenders. This program, based on a cognitive intervention strategy, involves a six week series of lessons whereby the inmates are given real world scenarios and asked to make decisions on how to handle them. Prior to the start of the program the inmates are to be given a survey type inventory and asked whether they agree or disagree with various...
A researcher studied the relationship between students' attitudes toward graphs and their performance in a statistics course. For a sample of students, data were collected on the following variables: . Tests (average number of questions answered correctly) Attitudes toward Graphs (o student thinks that graphs used in the course did not contribute to his or her learning: 1-graphs contributed to learning) Gender (0 = male, 1 = female) Academic Major (1 = business, 2 = liberal arts, 3-science and mathematics;...
1. Researchers study the impact of internalized bias on patient care. Nurses complete a survey which determines a score for their internalized bias from 0-100. Without knowing the internalized bias score, patients are asked to rank the subsequent care they receive from the nurse as poor, fair, good or exemplary. In this study your independent variable is measured at what level of measurement? Ratio Ordinal Nominal Interval 2. A study examines the relationship between interpersonal violence and health in women....
Does a student's attitude toward graphs affect his or her performance in an economics course? Researchers revisited this question in a follow-up study. [Source: Original study: Cohn, E., Cohn, S., Balch, D. C., & Bradley, Jr., J. (2004) The relation between student attitudes toward graphs and performance in economics. American Economist, 48(2), 41-52.] For a sample of students, data were collected on the following variables: Tests (number of test questions answered correctly during the semester) Attitude (0student thinks that graphs...
