In the introductory research methods class students draw samples of m&m candies and calculate appropriate statistics estimating the degree of precision of the sample results.
A new mask has been designed and fabricated in which it is simple to analyze small sample sized and the precision of the sample holder has been tested showing good data repeatability.
The precision of the sample plot measurements in describing the forest stand can be measured using the standard errors of the estimators of given forest characteristics, which depends, in part, on the spatial variation of the characteristics of interest within the forest.
This was done to increase the precision of the sample.
This might be due to the z-stage's moving precision or manufactoring precision of the sample.
To quantify the precision of the sample mean, we calculated the error propagation from the sum of the 95% confidence interval (±4%) and the additive systematic errors in kATP (+11 and −6%; Supplementary data), to give a coupling constant of 1.26−0.13+0.19 ATP/bp.
To increase the precision of the sample, prior to selection, the PAF was sorted by local authority (PCT within London) and the percentage of households with a head of household in a non-manual occupation (Socio-Economic Groups 1-6, 13), taken from the 2001 Census.
In bold: correlations for which the 95% confidence interval does not contain 0. As anticipated, the precision of the sample exposure estimate increased, i.e. s y decreased, with longer sampling durations for all three percentile variables, and for the percentile range.
As shown in Figure 2C, without the need of matched control sample, the precision of the single-sample mode of our pipeline was above 50% to identify pSNMs in healthy individuals when the allele fractions were 0.1-0.3 0.1-0.3
As expected, shorter samples led to decreased precision of the estimate; sample standard deviations correlated strongly with true full-shift exposure values.
