Distributions
Distribution of sample means
What is a pdf?
A type of non-parametric data that consists of names or categories
What is nominal data?
A type of error that produces a false positive, "innocent until proven guilty"
What is a Type 1 error?
A statistically significant portion of a population
What is a sample?
A term used to describe how well we know the mean of a dataset
What is the standard error?
This hypothesis is rejected if our t_data exceeds t_crit
What is the null hypothesis?
A term describing a range of estimates such that 95% of the time the true mean will be contained in that range
What is a Confidence Interval?
50th percentile, where one half of the data is on one side and the other half is on the other side
What is the median?
The smallest difference to reject the null hypothesis
What is the Least Significant Difference?
A term that describes where most of the data is in a given distribution
What is the Central Tendency?
The term that describes two variables that tend to vary together
What is correlation?
The term describing the risk of falsely rejecting the null hypothesis
What is Significance?
A theorem that states that for some sample sizes sufficiently large (n > 5), the means will be normally distributed regardless of the shape of the original distribution.
What is the Central Limit Theorem?
Error analysis that determines the uncertainty by multiple interacting variables
What is Gaussian Error Propagation?
An analysis of variance tool that uses Total Mean Square, Model Mean Square, and Error MS
What is ANOVA?
