Using data from a group of people completing the measure, it is possible to estimate this level of item difficulty (the item parameter) and place this along an interval logarithmic scale
Richter, is a logarithmic scale
that expresses the magnitude of a seismic disturbance in terms of the energy dissipated.
The result is shown on a logarithmic scale
, similar to the Richter scale method used in measuring earthquakes.
Since magnitudes are given on a logarithmic scale
, an 8.
This may not sound like much but since decibels are based on a logarithmic scale
, an increase of only three dB results in doubling of intensity.
A near-linear dependence of RMS roughness with the measurement length scale (L) is found on a double logarithmic scale
However, it is often more informative to explore age-specific incidence rates by logarithmic plots The age-specific rates were graphically analyzed on a logarithmic scale
and plotted as the log age-specific rate versus the log age at diagnosis (Figure 3).
GMTs of antibody and their confidence intervals were computed by transforming the results to a logarithmic scale
, assuming asymptotic normality conditions were satisfied on the scale and converting back to the original scale.
This is calculated on a logarithmic scale
so that an increase or decrease of just 10dB doubles the difference.
1, "Development Cost Trends," uses a scatter plot of various programs on a logarithmic scale
The Chart, in a logarithmic scale
, describes the breadth of capacity options that customers have for tape solutions, ranging from a 36GB single drive to multi-petabyte enterprise systems.
Devised by American geologist Charles Francis Richter, the scale measures the magnitude of earthquakes on a logarithmic scale
, so that a quake of magnitude 5 is 10 times more powerful than one of magnitude 4.
For estimation of correlations, we assumed that all pairs of congeners had joint normal distributions on the logarithmic scale
, and used maximum likelihood to estimate the correlation while accounting for the censored observations.
Since dB are on a logarithmic scale
like the Richter scale, adding 10 dB of processing gain means the system has 1/10th the noise of a system with no processing gain (0 dB).
For the analysis of CD62P expression, data were acquired in real time with a primary gate set on a dual-parameter histogram of forward light scatter logarithmic scale
(abscissa) and side light scatter logarithmic scale
