How many variables are measured in each row? 3. For each variable, would you describe it as primarily categorical or quantitative? If quantitative, what are the units? If categorical, is it ordinal or simply nominal? 4. Are these data a time series or cross-sectional? Explain briefly. 5. Do the data appear to have come from a designed survey or experiment? What concerns might you have about drawing conclusions from this data set?

Use equations (1.1.1 and 1.1.2) to determine the (1) absolute error and (2) percent error for a value of 4.422 g/cm³ determined for the density of titanium ( which the true density value is 4.506 g/cm³ 1. absolute error = (measured value - true value) = (4.422 g/cm³ - 4.506 g/cm³) = -0.184 g/cm³ 2. percent error = (absolute error)/(true value) \times 100% = (-0.184 g/cm³)/(4.506 g/cm³) \times 100% = -4.08% Question 1.1.5 In a series of experiments to determine the density of lead (Pb), the results in the second column of the table below were determined. Taking 11.343 g/ml to be the true value for the density of lead, complete the table by using equation (1.1.1) to calculate the absolute error and equation (1.1.2) to calculate the percent error for each density determination. Enter absolute error values in units of g/ml to the nearest 0.001 g/ml. Include the unit using the symbol g/ml. Enter percent error values to the nearest 0.01% without units and without the percent symbol.
