When,one,variable,causes,change,in,another,,we,call,the,first,variable,the,explanatory,variable*.,
The,affected,variable,is,called,the,response,variable*.,
In,a,randomized,experiment,,the,researcher,manipulates,values,of,the,explanatory,variable,and,measures
,the,resulting,changes,in,the,response,variable.,The,different,values,of,the,explanatory,variable,are,called,
treatments.,An,experimental,unit,is,a,single,object,or,individual,to,be,measured.
A,two-way,table,,also,known,as,a,two-
way,frequency,table,or,contingency,table,,is,used,to,show,the,relationship,between,two,______________
________variables,(,C→C,);,the,rows,show,the,categories,of,one,variable,,and,the,columns,show,the,categ
ories,of,the,other,variable.,,ANS,-categorical,variables,(,C→C,)
______________________.,These,represent,the,total,number,of,instances,that,fall,in,both,the,correspon
ding,row,and,header.
The,data,in,the,green,cells,show,_______________________________.,These,are,equal,to,the,sum,of,the,
number,of,individuals,in,the,corresponding,row,or,column.,,ANS,-
The,cells,in,yellow,show,joint,frequencies*.,These,represent,the,total,number,of,instances,that,fall,in,both
,the,corresponding,row,and,header.,
For,example,,data,in,the,"Male",row,and,"With,Autism",column,counts,the,number,of,males,with,autism.
The,data,in,the,green,cells,show,marginal,frequencies*.,These,are,equal,to,the,sum,of,the,number,of,indiv
iduals,in,the,corresponding,row,or,column.,For,example,,data,in,the,"Totals",column,and,"Female",row,sh
ows,the,total,number,of,females,in,the,study.,It,may,be,helpful,to,remember,that,marginal,frequencies,ap
pear,in,the,margins,of,the,table.
, The,bottom,,right,cell,(in,both,the,"Totals",column,and,the,"Totals",row),measures,the,total,number,of,ind
ividuals,in,the,study.
The,relationship,between,two,variables,that,are,both,quantitative,can,be,displayed,in,a,______________
____________.,,ANS,-scatterplot;
As,we've,seen,earlier,,every,point,on,a,coordinate,plane,can,be,represented,by,an,ordered,pair*,,(,x,,,y,).,H
ere,,the,x,-value,is,typically,the,_________________variable's,value,for,a,piece,of,data,,and,the,y,-
value,is,the,corresponding,value,for,the,________________________variable.,A,simple,way,to,remember
,this,fact,is,that,the,term,"explanatory",has,an,",x,",in,it.,,ANS,-explanatory,variable;,response,variable
Side-by-side,box,plots,are,a,good,choice,for,two-
variable,data,where,the,explanatory,variable,is,____________,data,and,the,response,variable,is,________
____,data.,,ANS,-Categorical,
Quantitative
Which,variable,,explanatory,or,response,,is,displayed,on,the,x,-axis,on,side-by-side,boxplots?,,ANS,-Side-
by-
side,boxplots,can,be,horizontal,or,vertical,,so,either,variable,(explanatory,or,response),can,be,displayed,o
n,the,x,-axis.
A,scatterplot,is,a,good,choice,to,display,two-variable,data,that,are,both,__________,variables.,,ANS,-
Quantitative
The,relationship,between,the,x,-variable,and,the,y,-variable,is,called,_____________.,,ANS,-Correlation
