Part I. RM overview. Identifying Variables and Levels of Measurement (0.5 points) The following are selected questions from a survey about sleep patterns and quality. Different levels of measurement are used here. Instructions: Identify the level of measurement used to measure the variables in each of these survey questions (Is it: nominal, ordinal interval or ratio?). Answer your questions in the format shown below the table (You may copy and paste the sentences below and enter the name of the level that applies): Olehden have night? praweronirane Scheel Joe What the of purch Work Feel sem d Fm Lagal ko los Althings considered his are you will this contossy the quality of you sleep!

The variable Level of life satisfaction (Q4) was measured using level of measurement APPENDIX Rules about rounding up numbers in your work. Rounding up numbers inflates them, which becomes a problem when those numbers are applied in successive operations - the results may become grossly overinflated at the end. Using Excel to prepare your assignments helps you avoid problems with rounding up. You may always use the function: "Decrease Decimall to reduce the number of decimals shown in cells (but those decimals are still used in calculations). - If you cannot use Excel to perform the operations, here are the basic rules that you must follow when performing calculations . For any numbers that end with decimal fractions, always retain minimum two decimal places, to begin with. If the numbers that you obtained from one operation are involved in other operations, you must increase the number of decimals for the results of each new operation For example: First operation: the result was 2.51 (minimum two decimals) Second operation: 2.51 x 0.67 = 1.682 (minimum three decimals) Third operation: 1.682 x 1.99 = 3.3472 (minimum four decimals) Ete., etc. You may round up your final results to two decimal places, again, but no less than two decimal places. For example: If the final result is 3.3472, it may be rounded up as 3.35 (but not as 33.3%) Any numerical results that show less than two decimal places will be treated as incorrect (unless they represent full integers) Part I.
