If you were to take three exams in your math classes and obtain scores of 86 , 75 , and 92 , you would calculate your mean score by adding the three exam scores and dividing by three -LRB- your mean score would be 84.3 to one decimal place -RRB- . If , in your math class , there are 40 students and 22 are men and 18 are women , then the proportion of men students is 22/40 and the proportion of women students is 18/40 . Mean and proportion are discussed in more detail in later chapters . Data may come from a population or from a sample . Lowercase letters like xx or yy generally are used to represent data values .
Please check all the words that can be used instead of the target word in the same context. Note that the morphology of the target (third person singular, past tense etc.) is considered to be applied to the candidate automatically in the process of paraphrasing.
