My son likes bowling so he watches bowling videos on my RUclips. Recently a good wired piece came up on the 7-10 split in my feed. Really interesting part about the piece. There was a study that said the 7-10 split is not the hardest spare to pick up on bowling. The observational study that looked at 500,000 spares concluded that the Greek Church, 4-6-7-9-10, was the hardest spare to convert with a conversion rate of 0.3% vs. 0.7% for the 7-10. It seemed pretty cut and dry with a half a million data points. One slight problem. The pro-bowler who was helping the team said 'Most of the time in a game time scenario you are going for count. You are going for the 3 on the right.' In other words given the odds when a pro-bowler get the Greek church they aren't tiring to pick up the spare. When they had the pro actually trying to pick up the spare he ended up converting it after about a dozen attempts, he never made the 7-10. They then tried it on a robotic bowling machine and the machine converted it about 40% of the time. The robot never converted the 7-10. The point? The 500,000 frame study was still just an observational study. Without the control, the study had no way of knowing that the bowlers weren't even trying to pick up the spare. As soon as they did a more controlled study the claim that the Greek Church was harder than the 7-10 fell apart in no time.
