Standard Deviation Measure of how spread out the data is from the mean
Low standard deviation Data set closer to the mean (accurate)
Higher standard deviation Data more spread out from mean (less accurate)
Equation for calculating standard deviation S = √∑(xi - x̄ )^2/n - 1
±1s of mean gives about what percent of the data set 68%
±2s of mean gives about what percent of the data set 95%
±3s of mean gives about what percent of the data set 99%
∑ The sum of
n Sample size
x̄ Average (or mean)
xi Data point
Equation for calculating standard error SEx̄ = 2/√n
Standard Error Indication of how well the mean of a sample (x̄) estimates the true mean of a population
Accuracy How close measured value is to the true value
Precision How close measured values are to each other
Equation for calculating chi square χ2 = ∑(o - e)^2/e
Equation for degrees of freedom df = n - 1
Template for null hypothesis There will be no significant difference between the data sets
Template for null hypothesis for Chi Square There will be no significant difference between what I observed and what I expected
Template for "acceptable" results statement from Chi Square Analysis The difference observed in the data were not statistically significant at the [*] level
Overlapping Error Lines (bars) Difference is not significant
Not Overlapping Error lines (bars) Difference may be significant

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:
