ECON1203 Business and Economic Statistics
Session 2, 2016
Major project:
The Fitness Challenge
Purpose
The!idea!is!of!this!assignment!is!to!simulate!a!professional!work!task!involving!statistical!analysis.!It!is!designed!
to! help! students! learn! about!what! is! involved! in! undertaking!basic! statistical! analysis! to! understand! a! real;!
world!problem,!and!communicating!the!results!of!this!analysis!to!business!stakeholders.!
Context and Problem
You!are!working!as!a!business!analyst!for!Your!Market!Consultants!Australia!(“YMCA”),!a!small!Sydney;based!
company!that!specializes!in!providing!statistical!consulting!services!to!Australian!companies!seeking!
intelligence!about!their!present!or!potential!customers.!LifeActive,!an!owner!of!several!large!fitness!centres!in!
Sydney,!contacts!YMCA.!!You!are!told!that!the!marketing!director!at!one!of!LifeActive’s!centres,!Rachel!Sprint,!
is!interested!in!using!market!research!and!statistical!analysis!to!build!a!group!fitness!program!that!meets!the!
needs!of!their!members!and!management.!
You! attend! a! breakfast!meeting! with!Ms! Sprint! and! a! senior! YMCA! consultant! to! discuss! her! concerns! in!
more!detail.! At!the!meeting,!Ms!Sprint!says:!
!
“So$the$situation$is$that$we$hired$a$market2research$firm$to$come$in$and$run$an$intercept$survey*$for$us,$which$
they$ did,$ and$ the$ data$ were$ collected$ in$ a$ single$ week$ in$ April$ 2016.$$ I’m$ now$ looking$ for$ someone$ with$
statistical$ expertise$ to$ analyse$ the$ data$ and$ give$ us$ some$ recommendations.$ Just$ which$ programs$ and$
instructors$will$create$the$perfect$balance$is$an$ongoing$challenge$for$our$business.$!
!
The$whole$ reason$we$did$the$ survey$ is$to$find$out$what$ sort$of$members$we’re$attracting$to$the$gym,$so$we$
have$a$better$idea$of$what$group$fitness$classes$might$do$well$in$the$gym$and$the$best$time$to$schedule$them.$$
You$see,$25%$of$our$fitness$instructors$are$terminating$their$contracts$at$the$end$of$next$year,$and$we$want$to$
know$ which$ kind$ of$ fitness$ instructors$ to$ approach$ in$ order$ to$ fill$ those$ vacancies.$ Some$ of$ our$ fitness$
instructors$ have$ also$ struggled$ to$ keep$ good$ class$ participation$ with$ consistently$ low$ class$ counts$ over$ long$
periods$of$time.$This$makes$me$wonder$whether$the$timing$of$those$classes$is$right$and$whether$their$workout$
program$is$a$good$match$for$our$members.!
!
My$sense$is$that$our$biggest$members$segment$is$high2income$young$women,$who$stay$at$the$centre$for$a$long$
time$and$are$the$main$participants$in$our$group$fitness$classes.$This$ would$ explain$why$ our$ Aerobic$classes$
like$SPIN$and$Abs$classes$ are$ generally$ doing$well.$I’d$expect$that$high2income$young$women$make$at$least$
20%$of$our$members,$but$I$am$happy$to$be$corrected$on$that.$We$ also$ have$ a$ community$ of$elderly$people$in$
the$neighborhood,$some$of$whom$are$regulars.!
!
So,$the$ first$ information$ I’m$looking$for$is$a$breakdown$of$member$types,$both$overall$and$by$group$fitness$
type.$$ I’d$also$like$to$know$whether$we’re$hitting$LiveActive$internal$minimum$thresholds$of$35%$of$members$
attending$group$fitness$classes,$and$45$minutes$spent$per$member$on$each$visit.$Some$ information$ about$ the$
types$ of$fitness$classes$ in$ which$ participation$ and$ time$ spent$ are$clustered$for$our$different$member$types$
would$also$be$of$use.$$Anything$you$can$tell$me$about$how$to$improve$our$appeal$to$our$main$member$types,$of$
course,$would$be$a$great$extra!”!

Based!on!these!comments,!that!afternoon!you!and!the!senior!consultant!draw!up!a!consulting!brief,!which!you!
send!to!Ms!Sprint,!who!approves!it!and!hires!you!to!perform!the!analysis!required!to!address!her!concerns.!!
Ms!Sprint!then!sends!you!an!Excel!file!containing!the!data!from!the!intercept!survey.!
!
You!are!given!the!responsibility!of!providing!a!statistical!analysis!of!these!data!and!for!producing!an!associated!
report!that!addresses!Ms!Sprint’s!concerns.!

Report
It!is!natural!to!associate!different!parts!of!the!project!work!with!the!coverage!of!relevant!material!in!particular!
Sharpe! chapters! and! lectures.! However,! remember! you! are! writing! a! professional! report,! not! providing! a!
sequence!of!answers! to!assignment!problems,! so!you! should!try! to!write!a! flowing! report!organized!around!
ideas,!not!methods.!

The!report!should!include!a!brief!Executive!Summary.!Ms!Sprint,!your!audience,!is!an!intelligent!person!but!she!
is!not!a!statistician.!Your!Executive!Summary!needs!to!be!non;technical!so!that!she!can!assess!what!you!have!
done!and!understand!your!basic!conclusions.!The!senior!consultant!at!YMCA!is!familiar!with!technical!analysis,!
and!will!be!reviewing!the!report!before!it!is!sent!out!to!the!client!to!ensure!that!the!conclusions!discussed!in!
the!Executive!Summary!are!reasonable!and!based!on!sound!statistical!analysis.!

substance!of!your!statistical!work,!the!presentation!of!the!material!will!also!be!considered.!Reports!should!be!
