The data represent a sample of 30 patients who visited a primary care clinic in Lubbock.

1. Identify the type of variable and level of measurement for each of the columns. (20 pts)

2. Would a pie chart be appropriate for age? Why or why not? (10 pts)

3. You randomly choose 1 of the 30 patients. What is the probability of choosing a Self Pay patient? (10 pts)

4. True or False: A statistic is a measure of a characteristic of a population. (10 pts)

5. Choose the most appropriate measure of central tendency for Body Temperature (check for skewness by graphing the data). (10 pts)

     a) Mean

     b) Median

     c) Mode

Answer 1

1.)

Age - It is a continuous variable on an integer scale

Health Status is a categorical variable with 5 levels. {1=well below avg, 2 = below avg, 3=avg, 4 = above avg, 5= well above avg}

Primary Payment Means,is a categorical variable with 3 levels. {0=None, 1 = Self-Pay, 2= 3d party}

Number of Primary Care Visits in 08 is a continuous variable on an integer scale

Patient's Body Temperature for 2018 Visits is a continuous variable on an decimal scale.

2.) Pie chart is generally used when data is in proportion/percentage of a whole. Here for age pie chart is not appropriate rather we can look at histogram.

3.) There are 9 self-pay patients. So probability of randomly choosing a self-pay patient is 9/30 = 0.3

4). True
