If you have already taken and passed the Content course, 14.310x Data Analysis for Social Scientists, and its proctored exam as part of the MicroMasters program in Data, Economics, and Design of Policy (DEDP), you do not need to retake the Content Course for the MicroMasters program in Statistics and Data Science (SDS).
The DEDP and SDS programs are separate programs, but they both include the Content course, 14.310x Data Analysis for Social Scientists. Each program has its own Assessment for 14.310x—for SDS it is the Assessment Course 14.310Fx; for DEDP it is the Proctored Exam at the end of 14.310x.
To earn credit towards the SDS MicroMasters Program Credential, you must complete the corresponding Assessment Course, 14.310Fx Data Analysis in Social Science: Assessing Your Knowledge.
