Question

You randomly visited several classrooms, and recorded the temperature in the classroom. For your convenience, type the following data into your RStudio: TempF=c(64,60,75,75,76,75,69,64,64,58,68,65,62,75,65,65,62,68,76,78,62,67,58,71) Find the standard deviation of the temperature variable.

Answer 1

To find the standard deviation of the temperature variable, you can use the 'sd()' function in R. Using the provided data, the standard deviation of the temperature variable is approximately 6.45, indicating that the recorded temperatures in the classrooms vary by an average of 6.45 degrees Fahrenheit from the mean temperature.

Step-by-step explanation:

To find the standard deviation of the temperature variable, you can use the 'sd()' function in R. In this case, the temperature data is stored in the 'TempF' variable. So, you can calculate the standard deviation by typing 'sd(TempF)' in your RStudio.

Using the provided data, the standard deviation of the temperature variable is approximately 6.45. This indicates that the recorded temperatures in the classrooms vary by an average of 6.45 degrees Fahrenheit from the mean temperature.
