[R] dercribe: to get the mean and sd, and print with paste

Of course you can hard-coded the standard deviation and mean GPA values.

like:

R 复制代码
#Using the command describe, tell what is the standard deviation and the mean GPA of the students in Year 4 (GE_survey_Y4)
#the variable name is Q19_actual_GPA
#Please write your code below
library(psych)
describe(GE_survey_Y4$Q19_actual_GPA)

and:

R 复制代码
standard_deviation <-0.31
print(standard_deviation)
mean_GPA1 <- 3.33
print(mean_GPA1)

but you have an alternative way to dynamically do it:

Create a df to store the sedcribe result and use stats$ to get the stored answer:

R 复制代码
stats <- describe(GE_survey_Y4$Q19_actual_GPA)
standard_deviation <- stats$sd
mean_GPA1 <- stats$mean

The instruction "#Please write a sentence with your answer below" is asking you to provide a written interpretation or summary of the results obtained from your code. This is often done in academic or professional settings to ensure that the reader understands the significance of the results without having to interpret the code themselves.

R 复制代码
If you have a variable statsanswer1 containing the number 7 and you want to report it in a sentence, you can use the paste() function to concatenate the text with the value of the variable. Here's how you can do it:

statsanswer1 <- 7
report_sentence <- paste("The answer is", statsanswer1)
print(report_sentence)

In this code, paste() combines the string "The answer is" with the value of statsanswer1 to create the sentence "The answer is 7". The print() function is then used to display the sentence.

Don't use "+" or "," directly, may work in Java or Python but not here.
