CHE101 MEASUREMENT AND ERROR ANALYSIS

(5 pts.) Class data: Use Excel to create a histogram (bar graph of mean values with standard deviation error bars) comparing the mean undiluted concentration values for all drinks tested by the class. Data sets where error bars overlap are not considered significantly different. Data sets where error bars do not overlap are considered significantly different. You will consider these ranges when comparing two average values (see the Claims and Evidence section below).

1.(5 pts.) Claims and Evidence: Provide Claims and Evidence for both your data and the class data. To determine whether two values are statistically different, report the range of values as the Mean ± Standard Deviation: e.g., 2.7 M ± 0.2 M, where 2.7 M is the Mean and 0.2 M is the SD. This notation indicates that the actual value is between 2.5 M and 2.9 M. If the two ranges overlap (i.e., the lower end of the larger number is less than the upper end of the smaller number), then the two numbers are not statistically different. If the two ranges do not overlap, then the averages are statistically different.Provide an overall assessment of the class data in terms of accuracy and precision. – e.g. did different groups agree with each other, where there any outliers, are the standard deviations large or small? You should make use of the RSD values when comparing the precision of the data
