9. Refer to Example 2.12 in Lesson2, Best Way to Determine Heart Rate. What type of variableis found in this example (categorical, measurement-discrete, ormeasurement-continuous)? Explain your choice.
Example 2.12. Best Way to Determine HeartRate
Consider an experiment where heart rate (heart beats/minute) ismeasured by three
different methods. Let’s consider three different methodsto determine heart rate.
Method 1: Count heart beats for 6 seconds &multiple by 10 to get heart beats/minute
Method 2: Count heart beats for 30 seconds& multiply by 2 to get heart beats/minute
2-12
Method 3: Count heart beats for 60 seconds
I tried this experiment on myself. I obtained six measurementsfor each of the three
methods. These results are found in Table 2.3.

Explanation / Answer
(categorical, measurement-discrete, ormeasurement-continuous) According to the given data the Heart rate is a continousvariable Therfore here the measurement is continous By using this data we can do the Anova one way.Related Questions
