Given a graph showing the relationship between daily caffeine consumption and
resting heart rate for some adults.
In the graph, the y-axis is labelled 'resting heart rate (bpm)' while the x-axs is labelled 'total coffee intake (cups)'
From the graph it can be seen that the y-value increases as the x-value increases.
Thus the phrases that describe the relationship between heart rate and daily intake of caffeine are as follows:
increasing heart rate and positive correlation

The graph used to represent relationship between daily caffeine consumption and resting heart rate for adults is describe with phrases,
- Increasing heart rate
- Positive correlation.
What is the correlation coefficient?
Correlation coefficient is used to calculate that how strong the relationship is between the two variables.
When there is a statically relationship exist between two or more variable, then they are said to be in correlation.
Types of correlation-
- Positive correlation coefficient- When there is the value of correlation coefficient is positive, then the value of one variable is increases with increase in other variable.
- Negative correlation coefficient- When there is the value of correlation coefficient is negative, then the value of one variable is decreases with increase in other variable.
The graph shows the relationship between daily caffeine consumption and resting heart rate for some adults.
There is two variable plotted on the graph.
On the x-axis of the graph the total coffee intake is represented.
On the y-axis of the graph the resting heart rate is represented.
In the given graph the heart rate of the adults is increasing with increase the number of coffee cup drink by the adults.
Thus the graph shows that the heart rate is in increasing order.
Now in the graph the the resting heart rate is increases with increase in total coffee intake value. Thus both the variables are increasing in the same direction. Thus it show the positive correlation.
Hence, the phrases which describe the relationship between heart rate and daily intake of caffeine is,
- Increasing heart rate
- Positive correlation.
