Hands-on Exercise
Use the covid_testing data set and everything you’ve learned so far to answer the following questions:
Clinics included
How many clinics participated in the study, and how many valid tests were performed on each one? Did the testing trend vary over time?
Number of clinics
Number of valid tests
Testing trend over time
Number of positive tests
How many patients tested positive vs negative in the first 100 days of the pandemic? Do you notice any difference with the age of the patients? Hint: You can make two age groups and calculate the percentage each age group in positive vs negative tests.
Number of positive tests in the first 100 days
Tests by age group
Processing times
Look at the specimen processing time to receipt, did the sample processing times improve over the first 100 days of the pandemic? Plot the median processing times of each day over the course of the pandemic and then compare the summary statistics of the first 50 vs the last 50 days
