Nata frenm. 1). 4. Give a Reported Value as is described in your lab manual, for the mass of the 10mL volume of water delivered by the beaker, the graduated cylinder and the pipet. Use your data and the data from 2 other students for your calculations. (See pages 1720 of the lab manual to see how to give a Reported Value for each. This includes the standard deviation and number of trials.) a. Student names for data used for question 4: i) Beaker g( mean SD,N= ii) Graduated Cylinder g( mean SD,N= iii) Pipet g( mean SD,N= b. If 10.00mL of water weighs 9.9997g (literature value) Which of the 3 types of glassware had the best accuracy when delivering a volume of 10mL c. Which of the 3 types of glassware had the least precision when delivering a volume of 10mL ? (look at SD value) The mean (or average) value, x, is: 78075 cells /mL (ignore sig. figs. for now). The standard deviation ( ds or SD) can be determined by the following equation: S=dsN1i=1N(xix)2 We should calculate how much each value deviates (xx) from the mean (note absolute value signs (II) below make the value positive). The square of each deviation (xx)2 can then be determined: (xx)178000780751178300780751178500780751177500780751Sum:(5625+50625+180625+330625)=567500ds(xx)2=75cells/mL=225cells/mL=425cells/mL4252=180625=575cells/mL5752=330625=41567500=434.932945752=56252252=50625 Note that the square root is taken of the total of the (xx)2 divided by the number of trials minus one. Since 4 trials (N) were done on the sample, we would divide by 3 . When calculating your SD, round off only at the end of the calculation when you are ready to report your value. (For example, we did not round 5752=330626 down to 330000 in the above calculation.) Once we have calculated the mean and standard deviation, we must report it properly. There are different conventions for how to report the mean and standard deviation. For this lab class, use the following method: 1. Calculate the value of the mean (78075cells/mL) and then the value of the standard deviation (434.932945 cells /mL ) without rounding off. 2. Round the standard deviation to one significant figure unless the SD begins with a "l". (In this case the 434.93 gets rounded to the hundreds place value, as is shown below.) If your SD value begins with a "1", then round off to 2 significant figures. (For example, if the SD was calculated to be 120.33, then the value would be rounded to 1.2102 ) 3. Round the mean to the same place value as the rounded standard deviation Report the value as the mean the standard deviation. If scientific notation is used, place the mean and standard deviation in brackets and include the scientific notation after the brackets. Units must be included and then followed by a bracket that defines what the numbers mean. Therefore the results should be reported as: (7.810.04)104cells/mL(meanSD,N=4)
