Answer:
Choice 1
Step-by-step explanation:
Let‘s go through each answer and analyze a
each.
<u><em>Choice 1</em></u>
<u>Parallel</u> means to lines with the same slope, they never intersect, ever, they always remain next to each other and never touch. This is true for the picture
<u><em>Choice 2</em></u>
<u>Perpendicular</u> means that two lines intersect at a right angle, however upon looking at the picture you can see this is not a right angle, but an acute angle. So it is not perpendicular.
<u><em>Choice 3</em></u>
A <u>Line Segment </u>means a line with dots on either end, symbolizing the end of the line. This is not a line segment because there are arrows on the ends, indicating these lines go on forever. This is not a segment
<u><em>Choice 4</em></u>
We already determined this is neither a segment nor perpendicular so it cannot be this choice
This leaves us with Choice 1.
I hope this helps!
Please give thanks and brainliest!
Answer:
The researcher should use correlation analysis for his studies.
Step-by-step explanation:
What is correlation?
Correlation is a statistical tool used to quantify the degree to which two variables are related. Through the correlation analysis, you evaluate correlation coefficient that tells you how much one variable changes when the other one does. Correlation analysis provides you with a linear relationship between two.
Types of correlation
1. Positive, Negative or Zero Correlation:
2. Linear or Curvilinear Correlation:
3. Scatter Diagram Method:
4. Pearson's Product Moment
Coefficient of Correlation:
5. Spearman's Rank Correlation
Coefficient:
