Discrete variables are variables whose values can only be whole numbers (integers), while continuous variables are variables whose values can be both integers and fractional (decimal) numbers.

Refer to the Journal of Experimental Social Psychology (Vol. 45, 2009) study of whether buying gifts truly buys love. Recall that study participants were randomly assigned to play the role of gift giver or gift receiver. Gift receivers were asked to provide the level of appreciation (measured on a 7-point scale where 1 = "not at all" and 7 = "to a great extent") they had for the last birthday gift they received from a loved one. Gift givers were asked to recall the last birthday gift they gave to a loved one and to provide the level of appreciation the loved one had for the gift. The researchers wanted to know if the average level of appreciation is higher for birthday gift givers than for birthday gift receivers. a. Why is this study designed? b. Specify the key elements of the study: experimental unit, response variable, factor, and treatments.

Suppose that the random variables Y 1 and Y 2 have means μ 1 and μ 2 and variances σ 1 2 and σ 2 2 , respectively. Use the basic definition of the covariance of two random variables to establish that C o v ( Y 1 , Y 2 ) = C o v ( Y 2 , Y 1 ).
