F1 India 2011: Free Practice Summary Stats

  1. 1. F1 2011 India (Practice)∗ A Statistical Graphics Review Tony Hirst† F1DataJunkie Blog License: CC-BY October 28, 2011 ∗ Source data used to generate this report was obtained from the Timing Information press releases publishedvia the F1/FIA Media Centre † @psychemedia, http://f1datajunkie.blogspot.com 1
  2. 2. 1 Free Practice SummaryWhat went on in the free practice sessions?1.1 Session Utilisation ChartsSession utilisation charts are an experimental chart type that show how each team made useof the practice sessions, identifying the time during the session when a lap time was recorded. Thecombined session utilisation chart shows the extent to which each car goes out, as well as usingcolour to denote stint length. There are some issues with the combined chart I need to fix: the carsneed to be identified as factors, thus removing non-existent car 13, and each car needs labelling(and ordering numerically) and highlighting with a minor(?) gridline. Add grey horizontal linesbetween each team to highlight the teams (so lines at 2.5:23.5 step 2).1.2 Session comparison chart (lap time, speed, position)The quickest lap comparison, fastest speed comparison and position comparison chartssummarise the best times/speeds recorded in each session along with the standings. The quickercars are the ones near the bottom of the fastest lap chart and the top of the speed chart. Notethat the name labels for the race drivers are used to identify the car that participated in eachsession. Some teams may utilise a third driver in the earlier practice sessions. Looking across the Classification rows and down the columns, there should be at most onceinstance of each symbol (evidence of that classified position for each of the sessions) in each rowand column. If there is a symbol missing, it may be hidden beneath one of the larger symbols. Sofor example, if the same car was placed third in free practice 2 and 3, we would only see the largersquare denoting the FP3 classification. (I wonder - can I specify the layer/height of a symbol asan aesthetic variable?) To do Add unit gridlines and labels to the position chart. Is it maybe worth including somesort of long stint summary? 2

  5. 5. 2 Team AnalysesThe Team Analysis reports provide a set of charts summarising the activity of each team duringeach practice session, in particular the range of laptimes and their distribution, by stint. I’m not sure the laptime distribution chart is that useful? To do Need a table for each team showing fastest lap per stint, and maybe some sort ofsummary of ’fast times’, esp. in longer stints (so eg more than N laps within X % of the fastestlap recorded by that team in that session?) I use the following identifiers for the teams: • RBR: Red bull Racing • MCL: McLaren • FER: Ferrari • MER: Mercedes • REN: Renault • WIL: Williams • FOR: Force India • SAU: Sauber • TOR: Toro Rosso • LOT: Team Lotus • HRT: HRT • VIR: Marussia Virgin 5
