Kom precis på att även jag har tappat bort mig till Uppsala en gång, hade två kompisar som gifte sig på Gimo Herrgård (nånstans nära). Tror jag var till Burger King och äta.... Trevlig gågata fanns där åtminstone!

Det enda jag minns från Uppsala var en att jag gick in på en nation och beställde tre flaskor champagne till galoppen på valborg. Efter det tog minnet slut Mycket lyckad valborg

Fan Ludas! Nu slog det ju, jag har ju varit i Uppsala en annan gång! - på Uppsjös (Uppsala akdemiska sjö- och kustsartillericorps) Uppsjöbal! Där var det galopp även! Var en heldel alkohol den helgen, sjukt roligt men stadssightseeing blev på lite mindre.

Tack för hjälpen med matteproblemet härromdan Bronto.
Här kommer nästa fråga för er mattesnillen (vet att strebban var sugen på förra matteproblemet).
Jag kör ett icke parametrisk ranking test, Mann-Whittney U för att säkerställa signifikansen mellan sample-grupper.
Problemet är att en grupp endast består av 0-värden (dvs hela grupp har värde 0 på samtliga samples). Ett ranking test går ju inte att köra då, men eftersom mina värden inte kan antas vara normalfördelade kan jag inte göra en ANOVA.
Visst fan måste jag kunna säga att resultatet är statistiskt signifikant om:

Mann-Whitney Test and CI: Sample X; Sample Y
.............N Median
Sample X 5 11,500
Sample Y 5 0,250

Point estimate for ETA1-ETA2 is 7,000
96,3 Percent CI for ETA1-ETA2 is (0,000;12,000)
W = 38,0
Test of ETA1 = ETA2 vs ETA1 not = ETA2 is significant at 0,0367
The test is significant at 0,0345 (adjusted for ties)

Således måste väl P<0,05 för en grupp som har 0 både mot Sample X och Y, även om inte denna statistiska metod vill låta mig bevisa det?
Har aldrig läst statistik, utan är mest självlärd, så kan ju inte direkt något annat sätt att lösa detta på, men alla former av Tukey etc. är uteslutet.
Jag vet att grupperna är sjukt små, men va fan

Ps. Är det bara två grupper som du jämför, varav den ena bara har 0 som värden?

Använder du SPSS? Eller vilket program kör man med nuförtiden? Då jag dylika greijer var det SPSS som gällde, och det fanns en bra bok typ "SPSS for dummies" (Fast så hette den inte, men nästan) som var gudsgåva, hade allt på ett vettigt sätt utskrivet och allt väl förklarat.
