Suppose we use random assignment to create two experimental groups, and then we collect two quantitative data values from each experimental unit in a sample. If we have a sample correlation coefficient that is very close to 1-1, then what can we conclude about our sample data?

• The explanatory variable increasing will CORRELATE with the response variable increasing in reality.
• The explanatory variable increasing will CAUSE the response variable to increase in reality.
• The explanatory variable increasing will CORRELATE with the response variable decreasing in reality.
• The explanatory variable increasing will CAUSE the response variable to decrease in reality.
