Line Graph

Histogram

Setting Up Axes

Titling Graphs

Interpreting Information from Graphs

Direct v Inverse Relationships

Reaction Rate

Standard Deviation & Standard Error

Bar Graph

display of data in discrete categories to compare variable conditions to each other

display of frequency of continuous data in categories to show distribution across variable

display of data that is connected in some way (ex: time, temperature)

Scatter Plot

used to identify correlation or trends between two variables when relationship is unknown

Task 1: What type of graph would you use to illustrate the data shown below?

axis titles

x: independent

y: dependent

consistent interval

Task 2: What would be an appropriate title for this graph?

informative & descriptive: what is the experiment & what is being measured?

standard deviation (s)

standard error (SE)

measures the spread (variance) in data

large s = a lot of variability in data

small s = data clustered around mean

how confident are you that your data is representative of the larger population?

on AP Biology Equations & Formulas Sheet

estimate of the likelihood the sample mean matches the actual population mean

mean +/- 1 SE = 67% confidence population mean within range

mean +/- 2 SE = 95% confidence population mean within range

+ slope

- slope

0 slope

change in dependent variable per unit of independent variable

reaction rate = slope of line

Task 3: Calculate the rate of oxygen production from 60 to 120 seconds.
