Words you should tattoo on you arm.
Little bit of this,
little bit of that.
How confident are you?
What's your hypothesis?
Not your Grandma's notation.
100
A summary measurement for an entire population.
What is a parameter?
100
The bell curve, symmetric and the empirical rule.
What should come to mind when you see the words "normally distributed"?
100
An interval of values that a researcher is fairly sure will cover the true, unknown value of the population parameter.
What is a confidence interval?
100
A proposed explanation made on the basis of limited evidence as a starting point for further investigation.
What is a hypothesis?
100
n
What is sample size?
200
The probability that an effect is not due to just chance alone.
What is statistical significance?
200
A number between -1 and +1.
What is a correlation coefficient?
200
The rough definition of "standard error."
What is the average difference between the statistic and the population parameter?
200
A value that would indicate that nothing of interest is happening.
What is a null value?
200
r
What is correlation coefficient?
300
The discipline of quantitatively describing the main features of a collection of data, or the quantitative description itself.
What is descriptive statistics?
300
The 3 main numbers associated with the empirical rule.
What are 68, 95 and 99.7?
300
To conservatively calculate the margin of error you do this.
What is taking 1 and dividing it by the square root of your sample size?
300
Probability values give you z-scores and z-scores give you this.
What are probability values?
300
"mu"
What is population mean?
400
The process of making conclusions about population parameters on the basis of sample statistics.
What is statistical inference?
400
When calculating a z-score you do this.
What is subtract the observed value from the mean and divide by the standard deviation?
400
I want a margin of error of 3%. This is roughly my sample size.
What is 1000?
400
The average IQ in our class is 101. Emma thinks it is much higher. The null hypothesis is our IQ=101. Our IQ is greater then 101 is called this.
What is an alternative hypothesis?
400
"x-bar" (x with a bar over the top)
What is sample mean?
500
The probability distribution of possible values of the statistic for repeated samples of the same size taken from the same population
What is sampling distribution?
500
The distance between a specified value and the mean.
What is a z-score?
500
Because you are statistician and conservative is no longer good enough you now use this format for your confidence intervals.
What is a sample estimate plus or minus the multiplier times the standard error?
500
The probability of obtaining a test statistic at least as extreme as the one that was actually observed, assuming that the null hypothesis is true.
What is a p-value?
500
"p-hat"
What is sample proportion?

e
n
