The student will design and carry out a survey. The student will analyze and graphically display the results of the survey. Instructions: As you complete each task below, check it off. Answer all questions in your summary. ____Decide what data you are going to study. EXAMPLES: Here are two examples, but you may NOT use them: number of M&M’s per small bag, number of pencils students have in their backpacks. ____Are your data discrete or continuous? How do you know? ____Decide how you are going to collect the data (for instance, buy 30 bags of M&M’s; collect data from the World Wide Web). ____Describe your sampling technique in detail. Use cluster, stratified, systematic, or simple random (using a random number generator) sampling. Do not use convenience sampling. What method did you use? Why did you pick that method? ____Conduct your survey. Your data size must be at least 30. ____ Summarize your data in a chart with columns showing data value, frequency, relative frequency and cumulative relative frequency. ____Answer the following (rounded to 2 decimal places): 1. x = 2. s = 3. First quartile = 4. Median = 5. 70th percentile = ____What value is 2 standard deviations above the mean? ____What value is 1.5 standard deviations below the mean?
