The researchers hypothesize that parents who participate in the program are more likely to have their children immunized, verses parents who do not participate. Two samples of parents and their children are formed randomly from records of a family practice clinic. One sample of parents participates in the program.

Of the 71 parents who do not participate in the program, 30 go on to obtain a complete set of immunizations for their child.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
