Question

The following data was collected in an experiment measuring the pressure of a gas (in atmospheres) as a function of temperature (in Kelvin). Temperature (K) Pressure (atm) 273.1 0.987 283.2 1.072 294.1 1.191 305.6 1.202 314.2 1.381 323.8 1.451 336.4 1.576 Plot this data in Excel with the independent variable on the x-axis and use Microsoft Excel to calculate the coefficient of determination (R2). Report the value of R2 here. Note: take care not to confuse the coefficient of determination R2 with R, the ideal gas constant. R2 is a statistical measure that we will include in graphs depicting linear relationships.

Answer 1

To plot the given data in Excel, follow these steps: Create a scatter plot with temperature on the x-axis and pressure on the y-axis. To calculate R2 in Excel, add a trendline and check the 'Display R-squared value on chart' option.

Step-by-step explanation:

To plot the given data in Excel, follow these steps:

1. Create a scatter plot in Excel with the temperature data on the x-axis and the pressure data on the y-axis.
2. Enter the given data into two columns in an Excel spreadsheet.
3. Select the data and choose the scatter plot option from the chart types.
4. Format the chart as desired.

To calculate the coefficient of determination (R2) in Excel, follow these steps:

1. Add a trendline to the scatter plot.
2. Right-click on the trendline and choose 'Format Trendline'.
3. Check the 'Display R-squared value on chart' option.

The calculated coefficient of determination (R2) will be displayed on the chart.

Answer 2

The coefficient of determination R2 calculated by Microsoft Excel is:

R2=0,974024991
