Alan T., a fantastic statistics lecturer from Macquarie University, kindly recommended to outstanding statistics texts to me:

• “Statistical methods for psychology” by David C. Howell, and
• “Applied multivariate statistics for the social sciences” by James P. Stevens.

Both of these were written with such clarity and insightfulness – they are actually statistics texts I will return to again and again. I highly recommend them to anyone interested in learning about introductory through to intermediate statistics.
