Document Summary
Notes: review session on feb. 3 5-6:30pm, location tba. For friday"s reading : interpreting statistics from a linear regression analysis: Beta = correlation between each predictor and criterion variable, statistically controlling for other predictors. B = the slope of the line of best t describing relation between predictor and criterion variable (i. e. a 1-unit increase in x is associated with an increase of b in y. P = the likelihood that we obtained this result by chance (i. e. this effect is not real - it is simply luck that we got this result; interpreted by multiplying it by 100%) Predicting hours of sleep per night - don"t worry about sd of b and beta. Co-sleeping - the hidden danger: evidence for: p. Majority of sudden and unexpected infant deaths during sleep occurred outside of crib. Bed-sharing associated with 5x higher likelihood of sids. Co-sleeping may be associated with thermal stress, airway obstruction, or rebreathing of parental expired air.
