How does a z-score indicate how unusual a data value is?
It shows us by telling us how far away it is from the mean.
What does standard deviation value indicate?
The standard deviation for a set of data is a measure of how much the individual observations are spread about their mean. A small value indicates that they are all tightly packed around the mean value whereas a large value indicates that the observations are not so close together.
What does a high F statistic mean?
A high F statistic would results in a lower Sig, or P value, which would indicate that your results are significant.
Does a large value for an F-ratio indicate that the null hypothesis is wrong?
I'm not really sure what the F-ratio is, but we just finished null and alternative ratios in our AP stats class. In our class, we calculuated a p-value, and if that value is smaller than the alpha-value (significance level) you have enough evidence to reject the null hypothesis. Sorry if this doesn't help.
What does a correlation coefficient value of negative two indicate?
A mistake in calculations! ;) If the calculations are done correctly then the sample correlation must lie within the closed interval [-1, 1].
Is tcid50 the same as viral titer?
Tes categorically speaking yes. The titer of the virus using the TCID50 procedure shall be expressed as the titre of the virus
The r value of insulation indicate resistance to heat flow?
yes the R-value does indicate resistance to heat flow
What does pH value of 6.46 indicate?
BASE
How do you administrate TCID50 and EID50?
When you mean administrate, does this mean procedure for TCID50 or calculation for use? In calculating for the TCID50 and EID50 of the virus in question, you can either use the Spearman-Karber formula or the Reed amd Muench formula. You will be able to determine the amount of virus per 0.1 ml or 1.0 ml depending on the amount used in the procedure. There are a lot of procedure available in the net for both tests. If the computation is 105 per 0.1 ml then there are 100,000 virus particles in that volume. If you need only 103 per ml then 1.0 ml the original suspension shall be diluted with equal volume of diluent (1.0 ml.)
What is the relation between EID50 and TCID50?
EID50 (50% endpoints infectious dose) is used to measure the amount of virus causing infection in the host, while TCID50 (50% tissue culture infectious dose) is used to measure virus infectivity in cell culture. They both represent the viral titer required to produce a specific response (infection) in a biological system, but EID50 is usually used for animal models, while TCID50 is used for experiments conducted in cell cultures.
What does the hexadecimal value 0 indicate?
It indicates the value zero in any base.
What do the first 3 bands on a resistor indicate?
The first 3 band on a resistor indicate the value of that resistor.
What does placing a smaller value before a larger value indicate in roman numerals?
Subtraction
What does a PR value on an ECG of 214 indicate?
27
What is the numerical value deci?
The prefix 'deci' is used to indicate one tenth the value of the unit.
What does a negative value for the standard potential indicate?
the negative value for a standard potential indicates that the reaction is not spontaneous.
What is the numeric value?
The prefix 'deci' is used to indicate one tenth the value of the unit.
