THINGS IM IFFY ON Flashcards
(40 cards)
In multivariate designs what establishes covariance, temporal precedence, and internal validity
covariance: correlational research
temporal precedence: longitudinal design
internal validity: multiple regression analyses
external validity in factorial designs
interactions show moderators
when given a factorial design table, how do you find if there is a main effect
average values across for each condition of the IV and compare them if theyre different, there is a main effect if theyre the same, there isn’t
In an independent 2x2 factorial with 4 cells, how many people are in each cell or condition
each condition or cell has different participants
In an within group 2x2 factorial with 4 cells, how many people are in each cell or condition
Each participant is in all 4 conditions or cells
In an mixed 2x2 factorial with 4 cells, how many people are in each cell or condition
each participant is in 2 out of the 4 conditions
how do you know if there is a 3 way interaction
compare the two 2 way interactions and if they are different there is a 3-way interaction if theyre the same, there isn’t a 3-way interaction
what is time series data
data with years, dates, or times, you can make an area or line plot
what is numeric data
any kind of data with numbers you can make point plots and histograms
what is categorical data
data with two or more groups or categories, you can make bar plots or pie charts
geographic data
data with locations or coordinates, you can make maps
geospatial data
data with locations ex: latitude, longitude, state, country
multimedia data
text, images, audio and video
network data
data that shows connections between elements ex: social networks, power grids, cloud networks and internet
what is data visualization
the graphical representation of information and data can be graphs, charts, or maps. can be a form of communication and storytelling. a way to organize large quantities of information, a way to assess trends and patterns in data
disadvantages to visuals
they can be misinterpreted, and they can be misleading. it may be hard to identify bias or inaccurate info
who needs data
everyone it is used in all jobs
how can you avoid misleading viewers
make multiple kinds of visuals for the same data set if they look different use your best judgement to pick the best one
external validity is most important in what kind of claim
frequency
when is the only time random assignment is used
during experimental designs to assess internal validity
why use small N designs
collect a lot of data from one person rather than a little from a lot of people
what are some advantages of case studies
experimental control, manipulation, studying special cases
what are some disadvantages of case studies
internal and external validity
stable baseline
multiple time points tested to reveal a stable baseline before the intervention occurs
