What is Tercile probability?
The International Research Institute for Climate and Society (IRI) issues seasonal forecasts of precipitation and temperature in the form of tercile-based categorical probabilities (hereafter called tercile probabilities), that is, the probability of the below-normal, normal, and above-normal categories (Barnston et al …
What does lower quartile tell us?
A quartile divides data into three points—a lower quartile, median, and upper quartile—to form four groups of the dataset. The lower quartile, or first quartile, is denoted as Q1 and is the middle number that falls between the smallest value of the dataset and the median.
Which quantile is equal to median?
middle quantile
The middle value of the sorted sample (middle quantile, 50th percentile) is known as the median.
What’s the difference between a tertile and a tercile?
Tertile (noun) Either of the two points that divide an ordered distribution into three parts, each containing a third of the population. Tertile (noun) Any one of the three groups so divided. “The first tertile results include January through April’s revenues.”.
When is a tercile not a nottertile?
They are nottertile (more common term in my experience) or tercile groups unless 89 or 90 and 109 or 110 are tertiles of the data, i.e. 1/3 of values are less than 89 or 90 and 2/3 less than 109 or 110.
How many cuts are there in a tercile?
A tercile contains one-third of the data with the cuts being lower third, middle third and upper third. A tercile is an element of that particular subset of data divided into three groups that is either lower, middle or upper thirds.
When to use interpolation to calculate the tercile parameters?
Generally, if the number of data entries is not a multiple of three, interpolation is used to calculate the tercile parameters. The other term the OP wants is merely, “data divided into three groups,” which although not implying interpolation at face value, does not exclude it either.
