What is an example of a reliable test?

taking the SAT three times and getting a 530 on the math section every time

a bathroom scale displaying very different results from one day to the next

What is hypothesis testing?

concluding information about relationships between variables based on evidence

summarizing data using descriptive statistics

measuring a variable of interest using an operational definition

setting up an experiment in terms of levels and variables

What is an operational definition?

defines a variable in terms of observable and measurable behaviors

defines a variable in terms of a hypothetical construct

used to determine the independent variable of an experiment

What's displayed in a frequency table?

the frequency of observations at each variable value

values outside of the variable's range of observed values

Based on the frequency table, what can be interpreted about how many pets owned?

most people own between 0-2 pets

A grouped frequency table depicts ...

data based on intervals rather than frequencies for specific values

just one variable (usually based on scale data)

the highs and lows of frequency distribution data

What seems to be the shape of the distribution represented in this histogram?

none of the options accurately describe the shape

Why do dot plots offer greater transparency as compared to summary statistics?

because each data point in a sample is displayed

because they allow summary data to be displayed visually

because values of the data are retained for later analyses

because they allow for comparison of participants across different measures

Based on the graph, what type of relationship exists between the two variables?

it's not possible to tell, given the information in the graph

there is no relationship between the two variables

In a pie chart, the size of each slice of pie represents what?

the percentage or proportion of each observed category

categorical and numeric variables arranged in intervals

the frequency distributions of a few data points

comparisons of a variable distribution across different categories

any unnecessary information in a chart that is distracting

spaced bars that cross each other to make squares

the interference of light by superimposed network of lines

A violin plot is a graph that includes what information?

response variability by displaying the middle score in a dataset along with indicators of the range of the middle 50% and 95% of scores

percentages of a whole and represents percentages at a set point in time

a possible relationship between changes observed in two different sets of variables

how something changes over time

What is central tendency?

the value around which the data seem to gather

M represents __ ; μ represents __

mean of sample ; mean of population

mean of population ; mean of sample

Why are random samples rarely used?

it's difficult to gain access to the entire population

there are a lot of misconceptions about randomness

it's not very effective in producing a sample that can be generalized to the population of interest

convenience sampling is easier and equally as effective in building a sample that can be generalized to the population of interest

What has to happen for successful replications to build a strong case for generalizability?

new context or a sample with different characteristics

similar situations or simple sample of participants

inconsistent contexts using different measures from the original study

use designs with experimental and control groups that also use random sampling

What is expected relative-frequency probability?

the expected outcome if an experiment is repeated many times

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

rating of our confidence that this event will occur

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

What is an example of an independent event?

flipping a coin many times and it being heads or tails

being the first person to the theatre and finding a good seat

not paying my power bill on time and having my power cut

not parking in my assigned parking space and getting a ticket

What are independent events?

the probability of one event is not influenced by the occurrence of another event

when the researcher is aware of both events happening

when the researcher does not have any knowledge about the occurrence of either event

the probability of one event is influenced by the occurrence of another event

A(n) ____ is a level of the independent variable that receives a manipulation. A(n) ___ does not receive the treatment.

experimental group; control group

control group; experimental group

If I do an experiment and the results do not support my hypothesis, I ...

would fail to reject the null hypothesis

would reject the null hypothesis

What has likely led to numerous numbers of type 1 errors being published?

journals tend to publish "exciting" findings over "boring" ones

journals tend to publish "boring" findings over "exciting" ones

journals tend to publish whatever results show no difference

journals tend to publish whatever results show a difference

A z score measures what?

how far away from the mean a score is in terms of standard deviation

how far away from the mean the score is in terms of sample size

how far away from the mode a score is in terms of population size

how far away from the median a score is in terms of standard deviation

What is the mean of the distribution of a set of z scores?

the same as the mean of the distribution of the raw scores

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