Reliability is to ___; validity is to ___

consistency; measures what it is intended to measure

measures what it is intended to measure; consistency

What is hypothesis testing?

concluding information about relationships between variables based on evidence

setting up an experiment in terms of levels and variables

measuring a variable of interest using an operational definition

summarizing data using descriptive statistics

What is an operational definition?

defines a variable in terms of observable and measurable behaviors

used to determine the independent variable of an experiment

defines a variable in terms of a hypothetical construct

What's displayed in a frequency table?

data that shows how often each value occurred

data points plotted against class midpoint

values outside of the variable's range of observed data

the number of observations within a given interval

When should a grouped frequency table be used?

data are measured on an interval scale and vary over a large range of continuous data

data are measured on a ratio scale and vary over a large range of discrete data

What is the shape of this histogram?

we cannot determine the type of distribution based on this histogram

Why do dot plots offer more transparency?

because they allow each data point in a sample to be displayed

because is allows a summary of data points to be displayed visually

because they allow the values of data places to be retained for later analyses

because they allow for a comparison of participants across different measures

Based on the graph, what type of relationship exists?

we cannot tell based on the information given

What type of data should we use with a bar graph?

independent variable is nominal or ordinal and the dependent variable is scale

data for an independent variable when there are very few levels and a scale dependent variable

the relation between two scale variables

include information about a distribution's middle score and overall variability

What is interpolation?

assumes that a value between two data points follows the same pattern

assumes that values beyond the data points will continue indefinitely

uses scaling to distort portions of the data

occurs when participants are preselected or self-selected to provide data

What is represented in a pie chart?

percent or proportion of each observed category through the size of each slice

percent or proportion of each observed category through the number of slices

information about a distribution's middle score and overall variability

the relation between two scale variables

unnecessary information in a chart that is distracting

large-scale interference patterns

spaced bars that are parallel to or cross each other

all the information needed on a chart

What does central tendency refer to?

the particular value that all the other data seem to be gathering around

the physical middle of our data

What is a convenience sample?

uses participants who are readily avaibable

when people volunteer for a research project

every member of the population has an equal chance of being selected

all participants have an equal chance of being assigned to any level

What is generalizability?

the ability to apply findings from one sample or in one context to other samples or contexts

the likelihood that a particular outcome – out of all possible outcomes – will occur

every member of the population has an equal chance of being selected into the study

when our demographics are all the same for our sample

What is personal probability?

rating of our confidence that this event will occur

the mistaken notion that the probability of an event changes with a long string of the same event

the expected outcome if an experiment is repeated many times

the likelihood that a particular outcome – out of all possible outcomes – will occur

What are independent events?

the probability of one event is not determined by the outcome of another event

the probability of one event is determined by the outcome of the other event

the probability of one event is only influenced by the outcome of another event

the probability of two events happening at once

The research hypothesis states...

there is a statistically significant difference

there is not a statistically significant difference

What is confirmation bias?

a tendency to pay attention to evidence that confirms one's prior belief

the mistaken notion that the probability of a particular event changes with a long string of the same event

the phenomenon of perceiving a relationship between variables even when no such relationship exists

rating of our confidence that this event will occur

What do journals consider an "exciting" finding?

failing to reject the null hypothesis

we cannot determine anything based on the information provided

Increasing sample size of a sample results in...

the distribution of scores will become more normal

the distribution of scores will become negatively skewed

the distribution of scores will become positively skewed

we cannot determine what will happen to the distribution

z scores measure what?

the number of standard deviations a particular score is from the mean average

the number of standard deviations a particular score is from the median

the increase of variability in scores

the decrease of variability in scores

Which of the following is a characteristic of a distribution of z scores?

the score as the mean of the distribution of the raw scores

the score that is equivalent to the 50th percentile in the raw score distribution

What is the relationship between the central limit theorem and sample size?

as sample size increases, the distribution of sample means assumes a normal curve

as sample size decreases, the distribution of sample means assumes a normal curve

as sample size increases, the distribution of raw scores assumes a positive skew

as sample size decreases, the distribution of raw scores assumes a negative skew

What is a z statistic?

when you calculate a z score for a distribution of means

a normal distribution of standardized scores

a way to convert individual scores from different normal distribution with a known mean, standard deviation, and percentiles

a normal distributions of z scores
