(Hint: Use Logger Pro to help you make the calculations. 87 APPENDIX C INTERFACES COMPATIBLE WITH LOGGER PRO. Determine the mean, standard deviation, and the standard deviation of the mean for the measurements. The Nano SD has internal storage and same functionality as the Meteobridge Pro. 85 APPENDIX B USING LOGGER PRO ON A NETWORK. Installed in the expansion slot (instead of datalogger). 43 IDEAS FOR USING LOGGER PRO IN THE CLASSROOM. so many of the measurements gave the same results. The collected data is provided in table below. Table 1: Rectangular wood object Enter the acquired data in Logger Pro. Logger Pro Short Table of Contents LOGGER PRO OVERVIEW. Use Logger Pro to find the mean value of each dimension and the standard deviation of measurements (STAT function). That estimate is within 2% of the actual sample standard deviation.COPYRIGHT © 1997-2000 Tufts University and Vernier Software & Technology ISBN 1-92ĭistributed by Vernier Software & Technology 13979 SW Millikan Way Beaverton, Oregon 97005-2886 (503) 277-2299 FAX (503) 277-2440 09/21/00 Objective: The objective of the lab is to become familiar with the Logger Pro software and Lab Pro interface in order to collect data. The estimated variance is the weighted average of the squared difference from the mean: In : var = np.average((mids - mean)**2, weights=n) The Logic Energy Wind Logger (LeWL) is a battery-powered device that works with one or two wind speed sensors, and/or a wind. Imagine now that we know the mean of the distribution for our errors exactly and would like to estimate the standard deviation. In this case, it is pretty close to the mean of the original data. The mean of the distribution of our errors would correspond to a persistent bias coming from mis-calibration, while the standard deviation would correspond to the amount of measurement noise. The estimate of the mean is the weighted average of mids: In : mean = np.average(mids, weights=n) Mids is the midpoints of the bins it has the same length as n: In : mids = 0.5*(bins + bins)
So far Ive been doing this manually using a shift register. I also need to get the random uncertainties, and to do this Ive got a separate loop running which does a running average, RMS and standard deviation of the mean (SDOM RMS / sqrt (N)) calc. I'll use numpy.histogram to compute the histogram: In : n, bins = np.histogram(x) I have a mathscript node which works out all the systematic uncertainties. In : x = np.random.normal(loc=10, scale=2, size=1000) Measurement range: Given in degrees, the measurement range tells you how much deviation the instrument is calibrated to detect. We'll compute the sample mean, variance and standard deviation of the input before computing the histogram. Change the increment of t to t += n*(bins - mean)**2īy the way, you can simplify (and speed up) your calculation by using numpy.average with the weights argument.
