Statistics is often cited as one of the more difficult topics examined in the Part 1 MRCOG. Some candidates avoid the subject and hope to compensate by higher scoring in other subjects. This is unwise as the statistical component of the examination is significant and is also an easy way to gain substantial marks. While writing questions for the Part I examination and running Part I courses, it became obvious that the types of statistical questions asked were very limited with a repetitive nature (though, of course, the numbers are changed). This synoptic chapter will give you the appropriate level of knowledge of statistics required for the Part I examination.
