• Median

• Mean

• Matrix

• Standard Deviation

Separates the higher and lower halves of data

• Mean

• Median

• Medium

• Deviation

Represent the Variability in the Data

• Standard Deviation

• Chi Squared

• Mean

• Error Bars

A way to represent data variability (How close values are to the mean)

• Mean

• Standard deviation

• Chi squared

• Number Matrix

Larger error bars represent what?

• A low standard deviation

• A large standard deviation

• in the middle standard deviation

• equal standard deviation

Used to determine the significance of the difference between 2 means

• qt-test

• t-test

• tea-test

• Quadratic Equation

There is NO significant difference

• abstract hypothesis

• hypothesis

• Void hypothesis

• null hypothesis

in Biological science, we use a standard value of p=____ to determine significance

• .005

• .5

• .05

• 5.5

is p is less than .05 we can confidently say that the means are significantly different and we ____________ the null hypothesis.

• reject

• accept

• except

• recharge

All graphs should have:

• Descriptive titles

• x axis labels

• y axis labels

• clear data labels
