- 10. Key Steps 1. Hide unnecessary decimal places – Hide them, don’t delete them 2. Use colour coding 3. Sort the data 4. Use indexes 5. Charts are clearer – but show less informaCon
- 11. Data oVen show decimal places – obscuring the informaCon. The data are oVen in quesConnaire order – usually not helpful. Example 2 % Agreeing Brand 1 Beautiful 20.88% Cheap 63.40% Friendly 71.20% Sexy 41.73% Strong 41.67% Traditional 31.66%
- 12. Hiding the decimal places, and moving the % sign make the data easier to read. Example 2 % Agreeing Brand 1 Beautiful 20.88% Cheap 63.40% Friendly 71.20% Sexy 41.73% Strong 41.67% Traditional 31.66% % Agreeing Brand 1 Beautiful 21 Cheap 63 Friendly 71 Sexy 42 Strong 42 Traditional 32
- 13. Colour coding shows us where the top and boQom is. % Agreeing Brand 1 Beautiful 21 Cheap 63 Friendly 71 Sexy 42 Strong 42 Traditional 32 Example 2
- 14. SorCng the data makes the story clear. Brand 1 is Friendly and Cheap, but it is not TradiConal or BeauCful. Example 2 % Agreeing Brand 1 Beautiful 21 Cheap 63 Friendly 71 Sexy 42 Strong 42 Traditional 32 % Agreeing Brand 1 Friendly 71 Cheap 63 Sexy 42 Strong 42 Traditional 32 Beautiful 21
- 17. Let’s quickly consider a more complicated case. Example 2b % Agreeing Beautiful Cheap Friendly Sexy Strong Traditional Brand 1 20.88% 63.40% 71.20% 41.73% 41.67% 31.66% Brand 2 64.50% 22.16% 40.02% 87.21% 96.24% 61.31% Brand 3 53.86% 48.80% 30.08% 71.52% 27.88% 28.12% Brand 4 93.97% 9.70% 19.89% 97.23% 96.99% 98.19% Brand 5 88.36% 12.73% 34.63% 92.70% 30.03% 26.98% Brand 6 20.61% 60.82% 55.34% 30.58% 75.00% 64.70% Brand 7 1.93% 72.02% 83.76% 11.47% 59.86% 28.94%
- 18. Simple story, 2 groups of brands. One (4,2,5,3) Sexy & BeauCful. Two (6,7,1) Friendly and Cheap. No advanced analyCcs. Example 2b % Agreeing Sexy Beautiful Traditional Strong Friendly Cheap Brand 4 97 94 98 97 20 10 Brand 2 87 65 61 96 40 22 Brand 5 93 88 27 30 35 13 Brand 3 72 54 28 28 30 49 Brand 6 31 21 65 75 55 61 Brand 7 11 2 29 60 84 72 Brand 1 42 21 32 42 71 63 Hide decimal places, move % sign, use colour coding. Two-dimensional sorCng, called diagonalisaCon.
- 19. Review 1. Hide unnecessary decimal places – Hide them, don’t delete them 2. Use colour coding 3. Sort the data – Two dimensional is called diagonalisaCon 4. Charts are clearer – but show less informaCon
