Question

A pediatrician is studying weight gain in infants. He divides them into 2 groups: breast fed and bottle fed. Further, he divides them into those whose mothers feed them on a timed schedule, and those whose mothers feed them when they cry on demand). Weight gain is the dependent measure. What type of analysis should you run? Select one: a. a regression ob. a one-way ANOVA O ca 2 x 2 factorial ANOVA d. a 2 x 2 correlation If o2 is calculated to yield the magnitude of effect estimates instead of n for a particular experiment, the o estimates would probably be Select one: O a higher and more biased. O b. higher and less biased. O c. lower and more biased. O d. lower and less biased.

Answer 1

1) for this we can use regression analysis

Here weight is response variable and breast feed and bottle feed, time of breast feed and time for bottle feed as predictors.

2) its lower and less biased answer.
