michelle is conducting an experiment in which she is evaluating the effects of reward magnitude and reward immediacy on classroom behavior. she has two levels of reward (low and high) and two levels of immediacy (daily and weekly) with four groups: low-daily, low-weekly, high-daily, and high-weekly. michelle's design is best described as
Fully crossed design
The factorial research design is also called a fully crossed design. This design consists of all possible combinations of their level across all the levels of the research design. It is also called a fully crossed design. This type of research allows the valuable variables cross combination and also shows the effect of all variables. In the experiment method, all variables have only two-level and four treatment combination in all that is called as 2*2 factorial design. In some factorial design, some unwanted or fractional levels can be omitted to make a useful combination.
2) D (it was on cognitive function)
3) C (It is a randomized, controller trial. there's a section on it and a randomized, controlled trial chart. Also it's more of a trial than study (says so at the end)
A customer loyalty program
A customer loyalty program is one of the type of marketing based program that is specifically designed to strengthen the relations between the organization and the consumers.
The main purpose of a loyalty program is that it helps in encourage and also motivating the various types of consumers for using the products and the services which is specifically related to the given program.
According to the given question, a customer loyalty program is best illustrating the given situation and the Daily needs reward zone is basically using this type of program.
Therefore, Customer loyalty program is the correct answer.
