#Reflection Questions

** How was the install process? Anything I should know for future students?

The installation process was a little bit difficult having a Mac and not being comfortable with this installation process or OneDrive, but I think I will get the hang of it wiht some more practice.

**Have you used any statistical software before?

Yes, In my K300 class, we used Excel and Jasp throughout the semester.

#Installing new packages

#install.packages("psych")
#install.packages("psychTools")
#If you wish to write text inside of a code chunk OR block out code so it does not run, add a "#" to the beginning of each line

Including Plots

You can also embed plots, for example:

Note that the echo = FALSE parameter was added to the code chunk to prevent printing of the R code that generated the plot.

When packages are installed, their names must always be enclosed by double quotation marks (““).

#calling packages to use in files

library(psych)
library(psychTools)

#call in sample data “epi.bfi” from the PsychTools package

data(epi.bfi)

#Run the summary function to get some basic stats on all of the dataset's variables 

summary(epi.bfi)
