Does research from international teams make a bigger splash? Researchers explored whether research conducted by multinational research teams had a bigger impact than research from teams with less international representation (Hsiehchen, Espinoza, & Hsieh, 2015). The graph here shows the relation between two measures: 

(1) The average number of authors of articles in each journal who are from a different country than the first author, 

(2) A measure that assesses the scientific impact of the journal with a higher score, indicating more influential research.

Description

The x-axis shows 0.0 to 1.6 at an interval of 0.04. The y-axis shows 0 to 30 at an interval of 5. Data from the graph are summarized as follows. All data are approximate.

0.0 to 0.4- 7 data points less than 5

0.4 to 0.8- 4 data points less than 15

0.8 to 1.2- 6 data points less than 15

1.2 to 1.6- 3 data points less than 25

a. In this study, are the independent and dependent variables nominal, ordinal, or scale?

b. What type of graph is this? Why did the researchers choose this type of graph?

c. In your own words, explain what the researchers found.
