One of four segments of a distribution that has been divided into quarters. For example, the second-from-the-bottom quartile of an income distribution is those whose income exceeds the incomes of from 25% to 50% of the population.
In statistics the quartile point is the spot where one quarter of the items in a series is on one side and three quarters are on the other side. For example, if a series of numbers was 1, 3, #, 4, 5, 7, 10, 20 and 30, the quartile point (#) would be between 3 and 4.
One of a set of numbers (a quantile) on the random-variable axis that divides a probability distribution into four equal areas. The three quartile points that lie between the extremes of the distribution are designated as 3 and are defined in terms of the distribution function () as follows: Thus, 2 coincides with the median. In empirical relative frequency tables, the quartiles are estimated by interpolation. The interquartile range is the distance from 1 to 3; half of this distance is called the semi-interquartile range (or quartile deviation) and is sometimes used as a crude measure of variability or spread.
Any one of the values in a frequency distribuion that divides the distribution into four parts of equal frequency. The first quartile is the number below which 1/4 of the values are found.
one fourth of the data points in a data set. Often, private equity investors are measured by the results of their investments during a particular period of time. Institutional investors often prefer to invest in private equity funds that demonstrate consistent results over time, placing in the upper quartile of the investment results for all funds.
The segment of a sample representing a sequential quarter (25%) of a frequency distribution. The boundaries are at the 25th, 50th, and 75th percentiles.
Statistical ranking used to measure the performance of a fund or manager. A quartile is one quarter of the total population; therefore a fund with a ranking in the first quartile (Top Quartile) is seen to outperform 75% of the market.
The value between consecutive intervals in a frequency distribution of four intervals containing one-quarter of the population.
A common statistical term used to define the performance of a fund. All the funds are divided into four equal groups and arranged in order of performance, from best to worst. So, 'top quartile' means the fund is in the top 25% of the whole group.
Segment of a sample representing a sequential quartes (2,5%) of the group. (First 5 out of 20 funds)
(statistics) any of three points that divide an ordered distribution into four parts each containing one quarter of the scores
Displays the distribution of the rates of return for the universe. The rate of return is reported in annualized time-weighted values. Appropriate market indexes are indicated at the side of each time bar. Each quartile segment within a bar contains 25% of the institutions in the universe for that time period. The median value is shown by a solid line on each bar. The upper and lower quartile breakpoints are shown as dotted lines on each bar. The quartile chart shows the rate of return for individual portfolios and allows an immediate comparison against the universe. The hash marks at the top and bottom of the quartile bar indicate the 5th and 95th percentile of the universe, respectively. (Click here to see a sample.)
The Direct Service Industrial (DSI) customers' load is divided into four quartiles.
Any of the three values that divide the items of a frequency distribution into four classes.
The investment industry divides performance into four equal groups.
The lower and upper quartiles (also referred to as the .25 and .75 quantiles) are the 25th and 75th percentile of the distribution (respectively). The 25th percentile of a variable is a value such that 25% of the values of the variable fall below that value.
One quarter range of percentiles; a student with a test placement of 75 or better (out of 100) would be in the first quartile.
Any one of four equal divisions.
The values which divide a frequency distribution or set of ranked observations into four equal parts.
A division of a spread of values divided into four. A statistical division, generally used in financial services to denote performance of, say, a particular type of fund. Comparisons of similar funds are shown in a league table which is divided into four quarters or quartiles.
A quartile for a data set is one of three data points that divide the set of data into four parts, each containing a quarter of the data. The first point marks the lower quartile boundary at the 25th percentile. The second marks the middle quartile (or midpoint of the data set), the median or the 50th percentile. The last marks the upper quartile (or 75th percentile) of a frequency distribution.
ne fourth of a sample or population.
The 25th percentile or the 75th percentile, called the first and third quartiles, respectively.
A statistical measure dividing a sample into four numerically equal groups. Thus top quartile in a funds management context means the top 25% of the fund managers in a particular category or asset class.
Segment of a sample representing a sequential quarter (25%) of the group. (First 10 out of 40 funds - first quartile, etc.)
A statistical term describing a division of observations into four defined intervals based upon the values of the data and how they compare to the entire set of observations.
In descriptive statistics, a quartile is any of the three values which divide the sorted data set into four equal parts, so that each part represents 1/4th of the sample or population.
