For a clock traveling at 0.3 c, the elapsed time measured by the observer is 5.24 meters (1.75 × 10 −8 s), while for a clock traveling at 0.7 c, the elapsed time measured by the observer is 7.00 meters (2.34 × 10 −8 s).
A return period, also known as a recurrence interval or repeat interval, is an average time or an estimated average time between events such as earthquakes, floods, [ 1] landslides, [ 2] or river discharge flows to occur. It is a statistical measurement typically based on historic data over an extended period, and is used usually for risk analysis.
Frame analysis (also called framing analysis) is a multi-disciplinary social science research method used to analyze how people understand situations and activities. Frame analysis looks at images, stereotypes, metaphors, actors, messages, and more. It examines how important these factors are and how and why they are chosen. [ 1]
In mathematics, a time series is a series of data points indexed (or listed or graphed) in time order. Most commonly, a time series is a sequence taken at successive equally spaced points in time. Thus it is a sequence of discrete-time data. Examples of time series are heights of ocean tides, counts of sunspots, and the daily closing value of ...
Candlestick charts are a visual aid for decision making in stock, foreign exchange, commodity, and option trading. By looking at a candlestick, one can identify an asset's opening and closing prices, highs and lows, and overall range for a specific time frame. [7] Candlestick charts serve as a cornerstone of technical analysis.
Decade (log scale) Four powers of 10 spanning a range of three decades: 1, 10, 100, 1000 (10 0, 10 1, 10 2, 10 3) Four grids spanning three decades of resolution: One thousand 0.001s, one-hundred 0.01s, ten 0.1s, one 1. One decade (symbol dec [1]) is a unit for measuring ratios on a logarithmic scale, with one decade corresponding to a ratio of ...
Effect size. In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of a parameter for a hypothetical population, or to the equation that ...
Frame-dragging is an effect on spacetime, predicted by Albert Einstein 's general theory of relativity, that is due to non-static stationary distributions of mass–energy. A stationary field is one that is in a steady state, but the masses causing that field may be non-static — rotating, for instance. More generally, the subject that ...
