Dec 16, 2015 · Coincidences attract our attention because they seem weird, odd, or unlikely. Their improbability stimulates wonder—“what are the odds of this happening?” Probability theory, which is a...
Aug 22, 2018 · We look at the cognitive processes through examples that people volunteer as they seem them as coincidences (often through diary studies), and then focus on looking at the chance and causal...
We can use odds to compare different probabilities, by computing what is called an odds ratio – which is exactly what it sounds like. For example, let’s say that we want to know how much the positive test increases the individual’s odds of having cancer.

Imagine it is the middle of winter and you and your friends are camping by a lake. You turn to your friend and ask, “What are the odds you jump in the lake?” Immediately your friend protests and says, “Zero!” You understand this to mean that there is no way your friend will be jumping in the freezing lake—but have you ever considered what “odds” re...
To understand the odds ratio, we first need to understand probability and odds. ProbabilityThe proportion of times an even is expected to occur in the long run, which are always a number between 0 and 1.refers to the likelihood that an event will occur. Probability is a number between 0 and 1, where 1 is a 100% chance that the event will occur. Let...
When working with odds ratiosA measure of association which measures the odds of an event happening in one group compared to the odds of the same event happening in another group., researchers are interested in the relationship an exposureAny factor, condition, or characteristic that may be associated with an outcome of interest. and an outcomeThe ...
There are three main interpretations for an odds ratio: no association, protective factor, and risk factor. If an odds ratio is equal to 1, this means that there is no association between the exposure and the odds of disease . This is because, for an odds ratio to be equal to 1, the odds of disease given exposure and the odds of disease given no ex...
Researchers use odds ratios in many aspects of research. From the testing of new medical techniques, to vaccination trials testing the effectiveness of vaccines, to examining the impact of environmental factors like pollution or UV rays, odds ratios can help researchers understand how exposures effect the odds of disease. Naturally, odds ratios are...

Probability refers to the likelihood of an event occurring. It can be expressed as a number (0.5) or a percentage (50%). Statistical tests allow psychologists to work out the probability that their results could have occurred by chance, and in general psychologists use a probability level of 0.05.
