For one week, every third customer who makes a purchase at MacBurger is asked a quick 2 question survey regarding what their favorite menu item is and what item they would most like to see added onto the menu. Do you believe the results of this surveyr would be valid? uhm please explain

    That sounds like a valid survey of the menu items at MacBurger. One out of three customers (33%) is certainly a large enough sample.

    The only problem I can see is that if this a national chain, then different restaurants in different parts of the country may have differing favorites.

    "Validity refers to the degree to which a study accurately reflects or assesses the specific concept that the researcher is attempting to measure"

    A survey is valid if it correctly answers the question that researcher was asking.

    In this case, the researcher wanted to know what people wanted to buy at this restaurant. Asking 1/3 of the customers these questions over a week's time assures that the answers have provided accurate answers to this question.
