BIOL 55 EXAM 1 TERMS (SJSU)
area under the normal curve - ✅✅ -1. The proportion of the population with the
characteristic described
2. The probability that a randomly selected
individual from the population will have the
characteristic
68%= SD 1
95%= SD 2
99.7%= SD 3 (means that 99.7% of ll scores fall between 3+/- standard
deviations
Central Limit Theorem - ✅✅ -The theory that, as sample size increases, the
distribution of sample means of size n, randomly selected, approaches a normal
distribution.
confidence interval - ✅✅ -statistical range, with a given probability, that takes
random error into account
dependent variable - ✅✅ -The outcome factor; the variable that may change in
response to manipulations of the independent variable.
descriptive statistics - ✅✅ -statistical procedures used to describe
characteristics and responses of groups of subjects
experimental design - ✅✅ -Experimental design refers to how participants are
allocated to the different conditions (or IV groups) in an experiment.
F value (ANOVA) - ✅✅ -Measurement of distance between individual
distributions. As F goes up, P goes down (i.e., more confidence in there being a
difference between two means). To calculate: (Mean Square of X / Mean Square
of Error)
✅✅-the thing that will be changed in each experiment
independant variable -
Mann-Whitney U test - ✅✅-determines whether 2 uncorrelated means differ
significantly when data are nonparametric
