In Chapter 4 (Task 7) we looked at data based on findings that the number of cups of tea drunk was related to cognitive functioning (Feng et al., 2010). The data are in the file tea_15.sav. What is the correlation between tea drinking and cognitive functioning? Is there a significant effect?

Chapter 4 (Task 7)

One of my favourite activities, especially when trying to do brain-melting things like writing statistics books, is drinking tea. I am English, after all. Fortunately, tea improves your cognitive function – well, it does in older Chinese people at any rate (Feng et al., 2010). I may not be Chinese and I’m not that old, but I nevertheless enjoy the idea that tea might help me think. Here are some data based on Feng et al.’s study that measured the number of cups of tea drunk and cognitive functioning in 15 people. Enter these data into SPSS and save the file as tea_15.sav.
