Across
- 2. Block Design In this experimental design, you divide the participants into groups based on a variable or characteristic that you believe will affect the response. Then, you randomly assign to subjects from each group to treatments.
- 5. the probability that the observed outcome would take a value as extreme or more extreme than observed if the null hypothesis were true.
- 6. proportion of terms within a distribution that are at or below the value that is being considered.
- 8. a measure used to tell how many standard deviations above or below the mean an observation lies - also known as a standardized score.
- 11. an acronym to help you remember when to use a Binomial Distribution.
- 15. a numerical characteristic of a population.
- 16. Random Sample Members from a larger population are selected according to a random starting point but with a fixed, periodic interval.
- 17. a regression line which makes the sum of the squares of the vertical distances from the data points to the line as small as possible.
- 20. Bar Graph A graphical representation of data in which the bars are divided into segments.
- 21. measures the direction and strength of a linear relationship between two quantitative variables - symbolized as r.
- 24. refers to the tendency of a process that tends to consistently over- or under-estimate the value of the population parameter.
- 26. Using the LSRL equation to predict y-values for an x-value outside of the given range of x-values is called _________.
- 27. Hypothesis hypothesis that the researcher hopes to confirm by rejecting the null hypothesis.
- 31. Probability Plot a graphical technique used for assessing whether or not a data set is approximately Normally distributed.
- 33. Chi Square Test of _______ in which proportions of categorical variables are tested to be the same across two or more populations.
- 36. A data value is an ________ if it's more than 3 standard deviations away from the mean in either direction.
- 37. Events Knowing one event occurs does not change the probability that the other event occurs.
- 38. Estimate a value based on sample data that represents a likely value for a population parameter.
- 39. an acronym to help you remember when to use a Geometric Distribution.
- 40. Level probability value that, when compared to the p-value, determines whether a finding is statistically significant.
- 41. Random Sample Individuals from a population are chosen so that each individual has an equal chance of being selected.
Down
- 1. Plot Look at this graph to answer the question "Is this linear model appropriate?"
- 3. Limit Theorem theorem that states that the sampling distribution of a sample mean becomes approximately Normal when the sample size is large enough.
- 4. These types of graphs are for _________ variables: Bar charts, pie charts & frequency tables.
- 7. a numerical characteristic of a sample.
- 9. Sample Choosing individuals that are the easiest to reach.
- 10. Variable These types of graphs are for _________ variables: histograms, dot plots, stem-and-leaf-plots, box plots, cumulative relative frequency graphs.
- 12. Sample Members of the population are grouped, then a set number of groups are randomly selected.
- 13. Distribution a distribution that takes on a bell-shaped curve and is roughly symmetric.
- 14. PLUS CONTEXT What is the acronym that we must use when describing a graph of a one-variable statistic?
- 18. For a certain x-value, the difference between the y-value on the linear model and the true y-value is called the ________.
- 19. Statistic a value (z-score, t-score, or chi-square value) used in a hypothesis test to help determine if the null hypothesis should be rejected.
- 22. Two Error the error made when a false null hypothesis is not rejected.
- 23. Pairs Design a design in which a subject is matched with another subject with similar characteristics.
- 25. Interval an interval that, with a given level of confidence, is likely to contain a population parameter.
- 28. Randomized Design In this experimental design, all experimental units have an equal chance of receiving any treatment. We do not group them by any common variable.
- 29. Random Sample Members of the population are grouped, then members from each group are randomly selected.
- 30. of Fit Test This test compares a set of observed categorical values to a specific claim.
- 31. Hypothesis hypothesis being tested - usually a statement that there is no effect or no difference between treatments. This is essentially what the researcher wants to disprove to support their alternative.
- 32. of Error Measure the uncertainty in the estimate of a parameter (AKA: critical value * standard error)
- 34. If a graph has no clear modes, the shape is ________.
- 35. One Error the error made when a true null hypothesis is rejected.
