He has been right 39% of the time.
More likely to be correct. If you are trying to make a prediction then the probability that you will be correct is related to the strength of the hypotheses on which the prediction is based. Assume that the prediction depended on 3 hypotheses all being correct. Each has a probability say 10 to1, 15 to 1, and 3 to 1. Then the probability against all 3 being correct would be ((11 times 16 times 4)-1) to 1.
Punxsutawney Phil, the famous groundhog, has been predicting weather on Groundhog Day since 1887. According to the Punxsutawney Groundhog Club, Phil's accuracy rate is often cited as around 39% to 40%. This means that while he has a fun cultural significance, his predictions are not particularly reliable when it comes to forecasting the arrival of spring.
My prediction is that it will decay after a half-life of more than 10^30 years. That is more than a quintillion times the current age of the universe.
That means that your prediction was wrong and that you should include your results in the conclusion and try to explain some of the reasons why your prediction was wrong and if it was wrong because you were doing the experiment wrong.
The Philles have been to the World Series 7 times, winning 2 (1980, 2008) and losing 5 (1915, 1950, 1983, 1993, 2009).
Since 1887 Punxsutawney Phil has: * Seen his shadow 97 times * Not seen his shadow 15 times * No recorded record 9 times
not grammatically correct, but mathematically correct
There was. It was very similar to the Christian's end times.
Both are correct.
It is not correct to say 'great times are now'; instead, say 'great times have come'.
Not necessarily. A prediction of what you believe to be true is usually called a hypothesis. A theory is an explanation of a set of related observations or events based on proven hypotheses and verified multiple times through experimentation.
The best estimate is 17.The chances are always the same:1/2
