The likelihood of familywise error increases as fewer comparisons are made within a set of data.
False
The likelihood of familywise error increases as more comparisons are made within a set of data
The likelihood of familywise error increases as fewer comparisons are made within a set of data.
Exercise 4.3. Counting exchanges and comparisons with Selection Sort Original data set: 60,30,15,51,97,44,37,33 Show how many exchanges and comparisons using the above data set for a selection sort and their totals. Pass Exchanges Comparisons 1 2 3 4 5 6 7 Totals
Setting the alpha level at 0.001 instead of the usual 0.05 increases the likelihood of type II error type I error rejecting the null hypothesis having a small n
data valu es in a 7. The 68-95-99.7 rule for normal distributions states that 95% of the mally distributed data set will be within 2 standard deviations of the mear Generate numbers with a distribution that has fewer than 95% of the data values within 2 standard deviations of the mean. Can you generate a set that has many fewer than 95% of the data values within 2 standard deviations of the mean? How small can you make that percentage?...
A measurement of the acceleration of gravity g is made and the data set is used to calculate a mean and a standard deviation. The mean is 10.00 m/s2, and the standard deviation is 0.67 m/s2. 1. What range of values for g would include about 70% of the data set? What range would include about 95% of the data set? 70% Range: to m/s2. 95% Range: to m/s2. If you have two sets of measurements, and know the mean and standard deviation of...
(use TUKEY for the multiple
comparisons)
Create a SAS data set by reading these data. As an interesting exercise, try reading three lines like this: 7.2 Two cholesterol-lowering medications (statins) and a placebo were given to each of 10 volunteers with total cholesterol readings of 240 or higher. After 6 weeks, the following total cholesterol values were recorded: Statin A: 220 190 180 185 210 170 178 200 177 189 Statin B: 160 168 178 200 172 155 159 167...
for the following data set, calculate the percentage of data points that will fall within one standard deviation of the mean, and compare the result to the expected percentage of a normal distribution (50,46,54,51,29,52,48,54,47,48)
Question 8
7. Which dáta set has the greatest standard error? Explain what this tells us about the averages (means) in comparison to all the values within that data set? (2 pts) Seti has the qrestest standard error because the s reotest stonaaro error 1s Small, and thot increoses the Sten size of set 8. Describe a basic research question and data sets where standard errors can be calculated. (2 pts)
At least 99% of the data in any data set lie within how many standard deviation of the mean? Use Chebychov’s Theorem.
How could you measure the middle of a data set? . calculate the standard error of the mean b. calculate the standard deviation c. calculate the mean d. calculate the range
im not only looking for correct answer. please explain why your
answer is correct.
on of analytical data is based upon the Normal Error curve (or Gaus confidence interval corresponds to approximately ± two)standard sian distribution curve). The 95% deviations (2σ) from the mean. This means that: ement has a 95% chance of being smaller in magnitude than the random error of a given measur 2σ. accurate as the true value. the average value for the set of data is...
