What else can I help you with?
When do you use the relative standard deviation instead of standard deviation?
Use %RSD when comparing the deviation for popolations with different means. Use SD to compare data with the same mean.
When we know the population mean but not the population standard deviation which statistic do we use to compare a sample to the population?
The sample standard error.
What are the advantages and disadvantages of coefficient of variation?
One the main advantage of using the coefficient of variation over the standard deviation to measure volatility is the fact that CV is normalized and can be used to directly compare different asset's volatility. The standard deviation must be used in the context of the mean of the data.
What is plotted on the x axis of a line graph?
The independent variable - if there is one. A variable that is common to a number of pairs of variables that you wish to compare. For example, if you want to compare height and mass at various ages, the age would be on the x-axis.
Paul wants to compare whether the prices of tangerines in two supermarkets differ significantly. He has been noting down the daily prices for the last few days and has found the difference in the samp?
part 2 means to be 20 cents. If the standard deviation of the distribution of the difference between sample means is 28 cents and we are testing the null hypothesis at the 95% confidence level, which statement is true?

How do you use Standard Deviation to compare students results?
Standard deviation is used to measure the variability or dispersion of students' results around the mean score. By calculating the standard deviation for each group of students, educators can understand how consistently students performed relative to the average. A lower standard deviation indicates that students' scores are clustered closely around the mean, suggesting similar performance, while a higher standard deviation indicates greater variability in results. This analysis helps identify students who may need additional support or those who excel beyond their peers.

What services as a standard of comparsion to evlauate the effect of the independent variable on a dependent variable?
It seems part of this question is missing. Perhaps the answer is that you might compare the effect to basic functions such as linear, quadratic, or exponential.
When to use a Z distribution?
A Z distribution, or standard normal distribution, is used when the sample size is large (typically n > 30) or when the population standard deviation is known. It is appropriate for hypothesis testing and confidence intervals when the underlying data is approximately normally distributed. Additionally, it is used for standardized scores to compare different datasets. If the sample size is small and the population standard deviation is unknown, a t-distribution is more appropriate.
What is the difference between a chi-square and t-distribution?
Chi-square is a distribution used to analyze the standard deviation of two samples. A t-distribution on the other hand, is used to compare the means of two samples.
How do you calculate coefficient of variation?
The coefficient of variation is calculated by dividing the standard deviation of a dataset by the mean of the same dataset, and then multiplying the result by 100 to express it as a percentage. It is a measure of relative variability and is used to compare the dispersion of data sets with different units or scales.
Using mean and mean absolute deviation to compare data quiz?
how should i know
Which data set has a greater spread why?
To determine which data set has a greater spread, you can compare their measures of variability, such as the range, variance, or standard deviation. A larger range or higher variance/standard deviation indicates a greater spread, meaning the values are more dispersed from the mean. Visualizations like box plots or histograms can also help illustrate the spread. Ultimately, without specific data sets provided, a direct comparison can't be made.
