Data analysisA question about data analysis appears below. Data is provided in a text field. Copy this data into a spreadsheet program to calculate the answers to the question. There is a link to a webform that can be used to calculate average and the standard deviation of a single column of numbers. You can either use this form or your spreadsheet program to calculate the average and standard deviation. Acceleration of gravity at earth's surface, $g\approx 9.81$ m/s², can be measured in a simple experiment with a pendulum. If the angle that the pendulum makes to vertical is small, the period is, $\large T\approx 2\pi\sqrt{\frac{L}{g}}.$ Five hundred students make pendula using string of different lengths and measure the period. Their results are given in the table below. |
