BIOL 1406: LAB EXERCISE 1
Objectives
How do scientists collect and analyze data?
After completing this exercise, you should be able to:
identify the names and functions of the laboratory items on display in the lab
explain what a random variable is, and distinguish between discrete and continuous random variables
use SI units when making measurements in lab
convert between different SI units
use the correct number of significant digits when reporting a measurement
identify the number of significant digits in a reported measurement
choose an appropriate measuring device when measuring distance, weight, or volume; and use it correctly
use the correct number of significant digits when reporting computed values
display data in a well-organized and clearly labeled data table
use a calculator to calculate the mean, percent error of the mean, and standard deviation of a list of measurements; and explain what these statistics tell us
use the appropriate statistics to compare the precision and accuracy of different measuring devices
explain what the Student’s t-test is used for, and how to interpret the results
use a spreadsheet program such as Excel to calculate the mean, percent error of the mean, and standard deviation of list of measurements
use a spreadsheet program such as Excel to carry out the Student’s t-test
