Only 75% of your course credits can come from online (web) studies. This means that if you are required to complete 6 credits, then 4.5 of them can come from online studies.
Online studies are convenient, and you can do them at home in your pajamas! Therefore nearly everyone wants to do online studies. Who wouldn’t? However, researchers with in-person studies need participants, too. Additionally, participating in a study in person gives you experience you would not get in an online study.
It is because of the online-study limit discussed above. When you attempt to sign up for an online study, you may see this message: “Sign-up prohibited. With this sign-up, you would exceed the maximum number of credits from Online Studies.”
Many online studies can be started right away. If this is the case, you should see a link that says “Complete Survey Now.” If you cannot start it right away, when you return to your list of studies, click on “View Study Website.” Do not wait until the time listed on the timeslot. For online studies, this timeslot is actually the deadline for when the study must be completed. If you wait until the deadline, you will not be able to participate. Some online studies require the researcher to send you a link. If this is the case, it should be clear to you when you sign up.
This is because the timeslot listed for an online study is actually the deadline when the study must be completed. See the previous question.
Be patient. Some online studies are credited automatically, and some are credited by the researcher. Wait at least 48 hours before contacting the researcher about any credits you feel you are missing.
