RESEARCH METHODS : CHOOSING AND CONSTRUCTING A GRAPH Flashcards
WHEN DO WE USE A BAR CHART
discrete data + non continous
data is divided into categories
everyone is only in one category
discrete data is data that is
counted not measured
what 5 things to remember when constructing a bar chart
clear title
equal intervak
bars not touching
columns labelled
axis labelled+ operationalised : (e.g mean imporvement (Depression score)
scatter grams are used in correlatinoal studies to
show relationship between two co variables
what to remeber when doing a scattergram
clearly labelled title
axis and operationalised(units)
equal intervals
only draw line of best fit required
when do we use a histogram
continuous data e.g weight
bars touch each other
what is the x axis on a histogram for
equal sized intervals of single category( x axis) e.g count
what is the y axis on a histogram used for
frequency within each interval (e.g weight kg)
what are the 4 things to remeber when constructing a histogram
clear title
bars touching
equal intervals
axis labelled
