Conclusion

• Don't be afraid of the numbers.
• As I wrote this, I used power for the first time.
• There are tools to help you (e.g. excel). Also a fair few people know about stats (e.g. psychologists).
• If you find someone whose stats don't work, don't trust them.
• Take your time, and troll the internet to find out about stats when you need them.
• For next week, read chapter 3 of Cresswell.
