That is, your memory span for numbers, relative to the memory spans of other students, is probably pretty similar to your memory span for words, relative to the memory spans of other students. Z-scores allow us to compare different measures relative to the mean and standard deviation of their respective distributions. How robust is this effect? Are there limits to this effect? Memory span is a common way of measuring some aspects of human memory. With z-scores you can compare how your memory spans compare to the distribution of memory spans for other students. A positive z-score indicates that your memory span is larger than the mean span of other students. A negative number indicates that your memory span is smaller than the mean span of other students. The mean and standard deviation of the memory spans of other students is given in the text before the trial-by-trial data table. Answer the questions using the data below. You will often find it helpful to sort the data and calculate values using a spreadsheet such as Microsoft Excel@, Sheets from Google apps, Open Office, or Numbers (Mac only). To import the data into a spreadsheet select and copy all the cells in the trial-by-trial data table below and then paste them into an open page of the spreadsheet. Use the trial-by-trial data to answer these questions. Question Answer Status Memory span for digits: (Your answer must exactly equal the correct value.) 5 Check answer Hint Correct Memory span for words: (Your answer must exactly equal the correct value.) 4 Check answer Hint Correct z-score for the memory span for digits: (The difference between your answer and the correct value must be less than 0.01.) Check answer Hint Incorrect z-score for the memory span for words: (The difference between your answer and the correct value must be less than 0.01.) Check answer Hint Not yet answered correctly Hint: Subtract the mean for words across all students and then divide by the standard deviation. O Type here to search hp ? W X 3:27 PM 11/2/2019 13
