5.2 Indekstal

Indekstal bruges til at få overblik over en udvikling. De er især nyttige hvis man vil sammenligne udviklinger.

Betragt følgende to tilskuerudviklinger:

.
Sæson 08/09 9/10 10/11 11 /12 12/13 13/14
Tilskuergennemsnit 16908 14372 12849 12600 9166 15931
Tilskuerudvikling for Brøndby IF
.
Sæson 08/09 9/10 10/11 11 /12 12/13 13/14
Tilskuergennemsnit 7777 7107 7212 7422 5800 8061
Tilskuerudvikling for FCM

Det er svært direkte at sammenligne de to udviklinger. Vi kan se at de begge starter godt, er i krise i 12/13-sæsonen, og slutter godt. Hvem har mon haft den bedste udvikling?

Det finder vi ud af ved at lave indekstal. Man laver indekstal ved først at vælge et basisår. Det er typisk det første år i udviklingen. Basisåret er udgangspunktet for sammenligningen og derfor sætter man værdien til \(100\) (som i \(100\%\)). Derefter udregner man de andre indekstal ved at finde ud af hvor mange procent den pågældende værdi udgør af værdien i basisåret.

Selvom indekstal egentligt er procentværdier, skrives de uden procenttegn.

  • Eksempel 5.2.1
    Vi beregner indekstallet for BIF for 11/12 sæsonen med 08/09 som basisår. Tilskuertallet for 11/12 er 12600 og tilskuertallet for basisåret er 16908. Derfor kan vi udregne:

    \[I=\frac {12600}{16908}=0{,}7452=75\%.\]

    Dvs. indekstallet \(I\) er \(75\). Vi laver et nyt skema:

    .
    Sæson 08/09 9/10 10/11 11 /12 12/13 13/14
    Indekstal 100 75

Øvelse 5.2.1

Nu er det din tur.

  • a) Regn resten af indekstallene for BIF.

Løsning 5.2.1

  • a)

    .
    Sæson 08/09 9/10 10/11 11 /12 12/13 13/14
    Indekstal 100 85 76 75 54 94
Procentpoint

Kigger vi på indekstallene for tilskuertallene for BIF, kan vi se at fra sæsonen 12/13 til 13/14 er indekstallet vokset med:

\[94-54=40.\]

Vi siger at indekstallet er vokset med 40 procentpoint. Procentpoint er altså forskellen mellem to indekstal og det er noget andet end den procentvise stigning. Vil vi have væksten i procent skal vi regne:

\[\frac {94-54}{54}\cdot 100\%=74\%.\]

Vi ser at stigningen på \(40\) procentpoint faktisk er en stigning på \(74\%\).

Øvelse 5.2.2

Her ses indekstallene for FCM:

.
Sæson 08/09 9/10 10/11 11 /12 12/13 13/14
Indekstal 100 91 93 95 75 104
  • a) Hvem vil du sige har haft den bedste tilskuerudvikling i perioden 08/09-13/14?

Løsning 5.2.2

  • a) FCM har været mere stabile over perioden og slutter også 10 procentpoint højere ned Brøndby IF.

Øvelse 5.2.3

Se på indekstallene for FCM i sæsonen 12/13 og 13/14.

  • a) Med hvor mange procentpoint stiger indekstallet fra 12/13 til 13/14?

  • b) Med hvor mange procent stiger indekstallet fra 12/13 til 13/14?

Løsning 5.2.3

  • a) Stigningen er på \(29\) procentpoint.

  • b) Stigningen er på \(39\%\).

Beregning af værdier ud fra indekstal

Ligesom man kan udregne indekstal ud fra nogle værdier kan man også regne baglæns hvis man har indekstallene, men ikke værdierne. Man skal dog have mindst en værdi før man kan finde resten.

Antag at en vare koster \(250\) kr. i 2005 som er basisåret og antag at indekstallet for varens pris i 2011 er \(130\). Vi kan så regne varens pris i 2011 ved at tage \(130\%\) af \(250\):

\[250\cdot 1{,}3=325.\]

Varens pris i år 2011 var altså \(325\) kr.

Øvelse 5.2.4

Nedenunder ses tilskuertallene for SønderjyskE:

.
Sæson 08/09 9/10 10/11 11 /12 12/13 13/14
Tilskuergennemsnit 3420 3419 3283 ? 3005 ?
Indekstal 100 ? 96 96 ? 102
  • a) Bestem de manglende værdier.

Løsning 5.2.4

  • a)
