**Multi Line Graph**** **

**Question 1**

Are there lifestyle changes that Wraparound care can support that would change the length of recovery for stroke patients?

**Graphing sample – Bar, Line, Pie or Cumulative **

Some suggestions…..

-number of smokers

-number of people with low, normal and high blood pressure

-number of obese and non-obese people.

**Graphing and measures of central tendency/dispersion for independent and dependent variables – Scatterplot, Clustered bar graph, Multi-Line graph, mean, median, variance and mode. **

Some suggestions……

– Recovery time vs Smoking status (contingency table comparison of mean, median, mode, variance etc. )

– Recovery time vs Blood pressure (clustered bar graph)

– Recovery time vs Age

**Hypothesis tests should be based on visual finding in the graphs **

Some suggestions……

– Recovery time vs Smoking status (independent t test)

– Recovery time vs Blood pressure (ANOVA)

– Recovery time vs Age in categories (Chi)** **

**Question 2**

Are there lifestyle changes that Wraparound care can support that would change the cost of recovery for stroke patients?

**Graphing sample – Bar, Line, Pie or Cumulative **

Some suggestions…..

-number of physically active patients

-number of people with low, normal and high blood pressure

-number of patients with high cholesterol.

**Graphing and measures of central tendency/dispersion for independent and dependent variables – Scatterplot, Clustered bar graph, Multi-Line graph, mean, median, variance and mode. **

Some suggestions……

– Recovery Cost vs Physical Activity (contingency table comparison of mean, median, mode, variance etc. )

– Recovery Cost vs Blood pressure (clustered bar graph)

– Recovery Cost vs Age

**Hypothesis tests should be based on visual finding in the graphs **

Some suggestions……

– Recovery Cost vs Physical Activity (independent t test)

– Recovery Cost vs Blood pressure (ANOVA)

– Recovery Cost vs Age in categories (Chi)

**Question 3**

Are there indicators in the medical history of stroke patients that Wraparound care can influence that would change the length of recovery for stroke patients?

**Graphing sample – Bar, Line, Pie or Cumulative **

Some suggestions…..

-number of people with atrial fibrillation

-number of people with low, normal and high blood pressure

-number of patients with history of angina.

**Graphing and measures of central tendency/dispersion for independent and dependent variables – Scatterplot, Clustered bar graph, Multi-Line graph, mean, median, variance and mode. **

Some suggestions……

– Recovery length vs atrial fibrillation (contingency table comparison of mean, median, mode, variance etc. )

– Recovery length vs Blood pressure (clustered bar graph)

– Recovery length vs Age

**Hypothesis tests should be based on visual finding in the graphs **

Some suggestions……

– Recovery length vs atrial fibrillation (independent t test)

– Recovery length vs Blood pressure (ANOVA)

– Recovery length vs Age in categories (Chi)** **

**Question 4**

Are there indicators in the medical history of stroke patients that Wraparound care can influence that would change the cost of recovery for stroke patients?

**Graphing sample – Bar, Line, Pie or Cumulative **

Some suggestions…..

-number of people with atrial fibrillation

-number of people taking no anti-clot drug, anti-clot drug A or anti-clot drug B

-number of patients with history of ischemic stroke. (1, 2 or 3 strokes in the past)

Some suggestions……

– Recovery cost vs atrial fibrillation (contingency table comparison of mean, median, mode, variance etc. )

– Recovery cost vs anti-clot drug taking status (clustered bar graph)

– Recovery cost vs Age

**Hypothesis tests should be based on visual finding in the graphs **

Some suggestions……

– Recovery cost vs atrial fibrillation (independent t test)

– Recovery cost vs anti-clot drug taking status (ANOVA)

– Recovery cost vs Age in categories (Chi)

**Question 5**

Are there indicators in the drug history of stroke patients that Wraparound care can influence that would change the cost of recovery for stroke patients?

**Graphing sample – Bar, Line, Pie or Cumulative **

Some suggestions…..

-number of people taking nitroglycerin for angina.

-number of people taking no anti-clot drug, anti-clot drug A or anti-clot drug B

-number of patients with history of ischemic stroke.

Some suggestions……

– Recovery cost vs nitroglycerin for angina (contingency table comparison of mean, median, mode, variance etc. )

– Recovery cost vs anti-clot drug taking status (clustered bar graph)

– Recovery cost vs Age

**Hypothesis tests should be based on visual finding in the graphs **

Some suggestions……

– Recovery cost vs atrial fibrillation (independent t test)

– Recovery cost vs anti-clot drug taking status (ANOVA)

– Recovery cost vs Age in categories (Chi)

**Question 6 – An advanced problem**

Is preventative surgery worthy of the additional expense for stroke patients?

**Graphing sample – Bar, Line, Pie or Cumulative **

Some suggestions…..

-number of people having preventative surgery

-number of people in small, medium sized and large hospitals.

-number of patients with history of ischemic stroke.

Some suggestions……

– Preventative surgery vs time to first event post attack **Hint: **group the times. (contingency table comparison of mean, median, mode, variance etc. )

– Preventative surgery vs cost of recovery (clustered bar graph)

– Preventative surgery vs Age

**Hypothesis tests should be based on visual finding in the graphs **

Some suggestions……

– Given patient had Preventative surgery is there a difference in length of recovery for smokers vs nonsmokers (independent t test)

– Preventative surgery vs time to first event post attack (group times) (ANOVA)

– Preventative surgery vs Age in categories (Chi)** **

**Solution**
