MA-08-4.l. I Studentswill analyzeandmakeinferences
from datadisplays(drawings,table/charts,
pictographs,
bar graphs,circlegraphs,line plots,Venndiagrams,line graphs,stem-and-leafplots,
scatter
plots,histograms,
plots.
box-and-whisker
MA -084.1.4 Students
will constructdatadisplays(Venndiagrams,
tables,line graphs,stem-and-leaf
plots,
circle graphs,scatterplots); explainwhy the type of displayis appropriatefor the dataand explainhow
misleadingrepresentations
affect interpretationsandconclusionsaboutdata.
MA -084.1.2 Studentswill explainhow differentrepresentations
of data(e.g.,tables,graphs,diagrams,
plots)arerelated.
Obiectives:
l. Studentswill be ableto identifudifferentdatadisplays.
2. Studentswill be ableto gatherdatafrom scatterplot andfind the correlationbetweenthe variables.
3. Studentswill be able to comparetwo differenttypesof datadisplaysand find a relationshipbetweenthem.
needed:
Resources/materials
l. Handouts
2. Graphs
Descriptionof Plan
1. Studentswill reviewthe differenttypesofgraphsthatareusedto displaydata.
2. The worksheethastwo parts.The first part asksthe studentsto analyzea scatterplot and gatherconclusions
from the graph.It alsorequiresthemto makeinferencesaboutcorrelationbetweenthe two given variables.
3. The secondpart of the worksheethasthe studentscomparinga bar graphand circle graphwith the samedata
displayed.The studentsareaskedto find the connection(relationship)betweenthe different representations
ofthe dataandto usethis relationshipto makeinferences
aboutchangesin the data.
