With just 3 flips, the proportion of times that heads actually land up may not even be close to 50 percent. With 1,000 flips, the proportion of times that the coin lands heads up is likely to be near 50 percent. In cases like flipping a coin, it is possible to calculate probability. Probability is the measure, expressed as a percentage, of the chance that a particular outcome will occur. That chance depends on the total number of possible outcomes. For instance, imagine that 10 million people enter a random drawing to win a car.

The researchers concluded that the average height of a student is greater than 6 feet. This is an example of .

A person is declared to be dead upon the irreversible cessation of spontaneous body functions: brain activity, or blood circulation and respiration. However, only about 1% of a person’s cells have to die in order for all of these things to happen. How can someone be dead when 99% of his or her cells are still alive?

00001 percent. Analysis of experimental data often includes calculations of probability. If a result is very unlikely to have occurred by chance alone, it is said to be statistically significant. In this context, the word “significant” does not refer to the result’s importance. It means that a statistical analysis shows the result has a very low probability (typically, less than a 5 percent chance) of being skewed by sampling error. As you will see in the next section, every scientific result—even a statistically significant one—has a probability of being incorrect.
