Background and rationale

● Peopleencounterdataeverysingledayanditisoftheutmostimportancethat we developtheskillsto interactwithdataandmakesenseofit.

● Thisunitisasingle-weekblockofcontentthatwill reviewthechildren’sunderstandingofvariousdata displays(particularlylineplotsandbargraphs,which were newin3rdClass)andextendtheir understanding by introducingsimplepiechartsanddatacards.

● Alsonewto4thClass,thechildrenwillbeaskedtoidentifythemedianvalue(middlevalueinanordered list)andthe rangeofvaluesinadataset.Previouslytheyexploredthedistributionofdata(i.e.howdatais spreadinadisplay)in3rdClass.Theywill revisemode(i.e.themostcommonoutcomeoccurringvalueina dataset)andtheproportionalityofthedata(e.g.inapiechart,thesizeofeachfractionisdirectly proportionaltoitsvalue),which were alsoexploredin3rdClass.

● At thisstage,itisimportantthatchildrenbegintoappreciatethedifferencebetweencategoricaldata(e.g. eyecolour,haircolour,gender,handedness,etc.)andnumericaldata(e.g.numberssuchasheight,age, timetakentotraveltoschool,distancefromschool,etc.).Whilecategoricaldatatendstobesimplerto organiseand represent,itisimportantthatchildren workwithnumericaldataalso,because youcan calculatethemedianinanumericaldataset,butnotinacategoricaldataset,sincethosevaluescannotbe ordered.

● ApplyingtheDataInvestigation Cycle(PPDAC: Pose,Plan,Data,Analysis,Conclusion)isanessentialpart ofthelearninginthisunit,asthechildrenwillbeengaginginsomeorallofthestepsineverylesson.The childrenneedtodevelopstrategiestocollectand recordinformationusingfirst-handdata–information thattheycollectontheir own by counting,conductingsurveys/polls,conductingexperiments,and/or usingmeasuringdevices.First-handdatashould relatetothechildrenthemselves,andcanincludethe schooland/orcommunity.Ultimately,itishopedthatthechildrenwillposeanddeveloptheir own investigativequestions,collectand recorddatainanefficientandorganisedway, communicatetheir understanding by answeringandaskingquestions,andcometoaccurateandappropriateconclusions, basedonthedata.

● Asthereisa Reviewand Reflect weekimmediately followingthisunit,itis recommendedthatthechildren usesomeofthistimetoconductfurtherdatainvestigations.Itisalso recommendedthatthechildrenare providedwithmeaningfulopportunitiesthroughoutthe yeartocollect, representandinterpretdata,as partofmathsand/orothercurricularareas.

DataInvestigation Cycle(PPDAC)

We typicallythinkofdataasbeingpresentedwithpremadegraphsandcharts,whichthenneedtobe read andinterpreted.Butin reallife, we allcollect,analyseanddrawconclusionsfromdataallthetime,without such representations.Babiesandchildrenareconstantlytakingininformation(data)aboutthe world aroundthem.Theirprocessingofthisdata(unconsciouslyandconsciously)isessentialtolanguageand cognitive development,decisionmaking,etc. Forexample,throughcollectingandprocessingdata, young childrenlearn:whichshapescanenterwhichholesinashapesorter;how rotatingpuzzlepiecesoften resultsinabetterfit;andhowblueand yellowpaintmixedtogethermakegreenpaint.As we getolder, we canusedatagainedthroughnewexperiencestolearnmoreaboutanyaspectofthe real world,andtohelp makeinformeddecisionsandtakeinformedaction.

Inthe real world,statisticianstypicallyusetheDataInvestigation Cycle.Thisconsistsofthefivestages involvedinprocessingdata:poseaproblem/question,plan,data,analysis,conclusion.Inexploringthestand unitofData,inallclasses,includingJuniorandSeniorInfants,itisexpectedthatthechildrenwillexperience all,orstagesof,theDataInvestigation Cycleasawaytousedatatosolve real-worldproblemsorquestions, thatare relevanttothechildren.

Investigativequestionsversussurveyquestions

Investigativequestionsarethebigquestionsthatshouldconsiderthewholesample/group,e.g. Whatare the favouriteice-creamflavoursofthechildreninourclass?

Investigativequestionsarealsooften reusedoradaptedtocreateatitle forthecompleteddatadisplay, e.g.Our favouriteice-creamflavours.

Surveyquestions(ifbeingused)usuallyevolvefromtheinvestigativequestionandare rephasedtobeasked ofanindividual respondent,e.g. Whatisyour favouriteice-creamflavour?

Poseaquestion

Askaninvestigativequestionthatis interesting, relevant, worthinvestigating andisanswerable.Invitethechildrento posequestionsthattheyfindinteresting, whilealsoguidingthemtowardsselecting questionsthatwillbe feasibletoanswer.

● Whatdo we wanttofindout?

● Whatisthequestion we wanttoanswer?

● Isitaninterestingquestion?

● Isitananswerablequestion?

● Isit worthanswering?

Forthe teacher, thisunpredictabilitybringsits ownchallenges,e.g.allowingthechildrenthefreedomtoinvestigate their ownquestionsandtotrytheirchosenmethods,evenif wewould rejectthequestions forbeing unanswerable,or rejectthemethodsasbeingineffectiveorinefficient.

WhiletheDataInvestigation Cycleisdescribedsequentially,the realitymayoftenbe‘messier’,wherethe childrenmaymove forwardsandbackwardsthroughstagesandmaygoaroundthecyclemorethanonce. Furthermore,dependingonthescopeofthespecificquestionbeinginvestigated,theDataInvestigation Cyclemay ‘fit’inonelesson,orthestagesmaybespread overanumberoflessons.And,dependingon theneedsoftheclass,theteachermaychooseaparticularstagetobethe focusofaspecificlesson. For example,whilethe focusofanyunitondatashouldnotsolelybeonansweringquestionsonmanufactured graphsanddatasets,itmaysometimesbeappropriatetospendtimedevelopingthesedataandanalysis skills,aspartof(orinpreparation for)predesignedtasksandassessments.

Commonmisconceptions anddifficulties

● Thechildrenmanymiscountormisinterpretsymbols,talliesorscales.

● Theymaystrugglewithcomparing,i.e.identifyinghowmanymore/fewerchoseXthan Y, or preferredXto Y.

● Theymaynotappreciatetheimportanceofthe‘rules’governingthecreationofthedifferentgraph types(e.g.accuracyandconsistencyinorganisationandpresentation,consistentsizeandspacing, andtheinclusionofagraphtitle,labelsanda key/legend).

● Theymaystruggletodrawaccuratelyandneatlythevariousgraphtypes.

● Theymayincorrectlyassumethatonesymbol,block,interval,etc.,always representsoneitem. (Encouragethemtoalwayslookcarefullyatthe featuresthattellusaboutthevaluesinthegraph− scale, key, symbols,etc.)

● Theymayneedextrasupportwiththe keytopic-specificlanguage(i.e.bargraph,pictogram,line plot,piechart, key, mode,median, range).

● Estimatewhat youthinkisthemedianinthisdata set.Explainwhy.

● Howmight we identifythemedianormiddlevalue?

Teachingtip

Inthisdataset,becausethereisanoddnumberof values,thereisaclearandobviousmiddlevalue/ number,whichisalsothemedian.Iftherewasan evennumberofvalues,thenthere wouldbetwo middlenumbers,which wouldthenbeusedto calculatethemedianorvalueinthemiddleof bothnumbers.(Strictlyspeaking,thisisthe averageofthetwonumbers. Average/meanwill beintroducedin5thClass.)

Allowthechildrentimetoexploreandinvestigate their ownstrategies. Possiblestrategiesinclude:

● Writingoutallthenumbersinanorderedlineon their MWBsoronsmallpiecesofpaper,and orderingthesetofindthemedian(whichis3)

● Countinginwards,dot by dot,frombothendsof thelineplotuntilmeetingatthemiddledot

● Countingthetotalnumberof responses/dots(29) andusingthisnumberto workoutthemiddle response/dot(which wouldbethe15th)andthen countingfromeitherendtolocatethepositionof the15thdot(inthecolumn for3absences).
