Education/ exams company need a qualified data scientist/statistician/ to help me create two statistical models and visualise data -- 2

Problem 1:

We run an exam marking company and need help creating a statistical model for evaluating the 'inter-rater reliability'- between teachers that grade essays.

By this I mean, if several teachers grade the same essay, how do we work out how reliable the marking is?

This includes working out the mean, standard deviation, and "cronbach's Alpha". This will help us work out how reliable each teacher's marking is.

See notes on page 12 of: [login to view URL]

We need to turn this into graphs and visualisation as per those attached.

Taidot: Tilastotiede, Tilastoanalyysi, SPSS Statistics, Datatiede, Data Visualization
