What is a sample statistics?
It is a value calculated from the sample values only.It is a value calculated from the sample values only.It is a value calculated from the sample values only.It is a value calculated from the sample values only.
What is the sample size for standard deviation?
There is no such thing. The standard error can be calculated for a sample of any size greater than 1.
Is work settings nominal or ordinal?
They are nominal.
What level of measurement is required to determine the mode?
nominal
What does the term coefficient of variation mean?
The Coefficient of Variation is a ratio showing the degree to which individual points of data in a sample deviate from the mean. It is calculated by taking the standard deviation of the sample and dividing that by the mean of the sample. It can be useful for comparing different data sets because it is a ratio (or percentage) and not an absolute number.

What is nominal moment?
Nominal moment is the entire calculated moment after applying load...
What is the acid concentration of a sample of acid rain with a pH of 4.20?
The acid concentration of a sample of acid rain with a pH of 4.20 is 10^(-4.20) mol/L or approximately 6.31 x 10^(-5) mol/L. This is calculated by taking the negative base-10 logarithm of the hydrogen ion concentration in the solution.
Can a pH of a water sample be calculated from a knowledge of its acidity?
Yes, the pH of a water sample can be calculated from its acidity. pH is a measure of the concentration of hydrogen ions in a solution, which is related to its acidity. The formula to calculate pH from acidity is pH = -log[H+], where [H+] is the concentration of hydrogen ions.
Which of these is calculated in current dollar values?
nominal GDP
If a 25 g sample of sugar was dissolved in 50 g of water The concentration of the solution is?
The concentration of the solution is 33.33% sugar, calculated as (25 g sugar / 75 g total mass) * 100%.
A numerical value calculated for a sample is called a?
A numerical value calculated for a sample is called a descriptive statistic.
Calculate specific rotation?
The specific rotation of a compound is calculated using the formula: Specific rotation = observed rotation / (concentration in g/mL * path length in dm)
When calculating the cost of capital how should the share premium be calculated?
share premium could be calculated as by getting the difference between the market price of the share and its nominal price. Formula: Share Premium= Market Price - Nominal Price
How chlorine is calculated by using chlorotex reagent?
Chlorotex reagent usually contains DPD (N,N-diethyl-p-phenylenediamine) which reacts with free chlorine to form a pink color. The concentration of chlorine in a sample can be determined by measuring the intensity of the pink color using a spectrophotometer or a colorimeter and comparing it to a standard curve. The higher the intensity of pink color, the higher the concentration of free chlorine in the sample.
How do you calculate ic50 for antioxidant activity?
Scavenging capacity (%) = 100 - [(absorbance of sample - absorbance of blank) × 100/absorbance of control] The tests were done in triplicate. The IC50 values were calculated by linear regression of plots, where the abscissa represents the concentration of the tested plant extracts and the ordinate the average percent of scavenging capacity. The concentration of sample required to scavenge 50% of DPPH (IC50) were determined.
What is the concentration of carbon dioxide in this sample?
The concentration of carbon dioxide in a sample can be measured in various units such as parts per million (ppm) or percent (%) depending on the method used for analysis. Common methods include gas chromatography or infrared spectroscopy. It is important to specify which method was used to determine the concentration of carbon dioxide in the sample.
