- Inter-rater reliability. In statistics, inter-rater reliability, inter-rater agreement, or concordance is the degree of agreement among raters. It gives a score of how much homogeneity, or consensus, there is in the ratings given by judges.

Correlations, Reliability and Validity, and Linear Regression With the exception of interrater reliability and content validity, all other estimates usually involve the calculation of a type of correlation. Multiple estimates may be used to evaluate the properties of an instrument in certain situations.

- Reliability is a measure of the internal consistency and stability of a measuring device. Validity gives us an indication of whether the measuring device measures what it claims to. Internal consistency is the degree in which the items or questions on the measure consistently assess the same construct.

Travel Time Reliability: Making It There On Time, All The Time Travel time reliability measures the extent of this unexpected delay. A formal definition for travel time reliability is: the consistency or dependability in travel times, as measured from day-to-day and/or across different times of the day.Figure 2 further illustrates travel time reliability with data from a major commuter route in Seattle, Washington.s with the buffer index, a 95th percentile travel time is used. Other percentiles, such as the 85th, 90th, or even 99th percentile, could be used depending upon the desired level of reliability. For example, a lower percentile may be used in calculating reliability measures for less critical routes or trips.

Why Does a Lawnmower Backfire? When backfires occur as your lawnmower idles or as you're turning off the engine, the most likely problem is that you're slowing your engine speed too fast. Moving quickly across your yard builds up the engine speed, and if you shut it off suddenly, the engine could pump gas into your muffler where the gas could ignite.

Repeatability Repeatability methods were developed by Bland and Altman (1986). If the correlation between separate administrations of the test is high (e.g. 0.7 or higher as in this Cronbach's alpha-internal consistency-table), then it has good test–retest reliability.

- Test Reliability and Validity Defined. Test reliablility refers to the degree to which a test is consistent and stable in measuring what it is intended to measure. Most simply put, a test is reliable if it is consistent within itself and across time. To understand the basics of test reliability, think of a bathroom scale that gave you drastically different readings every time you stepped on it regardless of whether your had gained or lost weight.

- What are R-R intervals? Heart rate variability (HRV) is the measured changes of the time intervals (in milliseconds) between successive heart beats called R-R intervals, or interbeat intervals (IBIs). Unlike heart rate (HR) that averages the number of heart beats per minute, HRV looks much closer at the small fluctuations of the heart that occur in response to internal and external events.

Internal Rate Of Return (IRR) The internal rate of return is a useful metric used to compare potential investments that may having differing time horizons or cash flow patterns. Generally speaking, the greater the IRR, the greater the relative expected return after accounting for the time value of money.

What is 'Internal Rate of Return - IRR' DEFINITION of 'Internal Rate Of Return-IRR'. A metric used in capital budgeting measuring the profitability of potential investments. Internal rate of return is a discount rate that makes the net present value (NPV) of all cash flows from a particular project equal to zero.IRR calculations rely on the same formula as NPV does.hat is the relationship between the hurdle rate (MARR) and the Internal Rate of ... In capital budgeting, projects are often evaluated by comparing the internal rate of return, or IRR, on a project to the ...

Reliability and Consistency in Psychometrics Reliability refers to the consistency of a measure. 1  A test is considered reliable if we get the same result repeatedly. For example, if a test is designed to measure a trait (such as introversion), then each time the test is administered to a subject, the results should be approximately the same.

Upon FERC’s approval, NERC’s Reliability Standards became mandatory within the United States. These mandatory Reliability Standards include CIP standards 001 through 009, which address the security of cyber assets essential to the reliable operation of the electric grid.

What is the interquartile range? Confidence votes 114. Like the standard deviation, the interquartile range (IQR) is a descriptive statistic used to summarize the extent of the spread of your data. The IQR is the distance between the 1st quartile (25th percentile) and 3rd quartile (75th percentile). Q3 - Q1 = IQR. To find these numbers you must divide your data set in half, and find the median of each half and that will be your Q1 and Q3.

Internal rate of return The internal rate of return (IRR) is a method of calculating rate of return. The term internal refers to the fact that its calculation does not involve external factors, such as inflation or the cost of capital. It is also called the discounted cash flow rate of return (DCFROR).

- The interquartile range (IQR) is a measure of variability, based on dividing a data set into quartiles. Quartiles divide a rank-ordered data set into four equal parts. The values that divide each part are called the first, second, and third quartiles; and they are denoted by Q1, Q2, and Q3, respectively.
