sol:-ANOVA test requires normally distributed and continuous data.
so option (A) is correct.
1)since it is a parametric statistical technique used to compare datasets.
2)It is a statistical technique that assesses potential differences in a scale-level dependent variable by a nominal-level variable having 2 or more categories
Therefore ANOVA can be used in three ways -one way,two way,and N way ANOVA.
The ANOVA test requires what type of data? Select one 0 a. normally distributed and continuous...
Select the appropriate response a)The bootstrap assumes that data is normally distributed b)The bootstrap is applicable for any distribution of independently identically distributed random samples c)The bootstrap is applicable only to large samples Select the appropriate answer a)The bootstrap provides a procedure for estimating the uncertainty of parameter estimates b)The bootstrap provides a closed form formula for computing the uncertainty of any statistics c)The bootstrap provides an exact measure of uncertainty of distribution parameters Select the appropriate answer a)The bootstrap...
To determine if a set of ungrouped raw data is normally distributed, what test statistic would we use? Select one: a. A z-statistic b. An F-statistic c. Anderson-Darling d. A chi-square
Determine whether the given value is from a discrete or continuous data set. When a car is randomly selected, it is found to have 3 wipers. A. A discrete data set because there are a finite number of possible values. B. A continuous data set because there are infinitely mamy possible values and those values cannot be counted. O C. A continuous data set because there are infinitely many possible values and those values can be counted. OD. The data...
student is using ANOVA to test 3 samples of data. Each sample has 6 data values. If she uses a - 0.05, what should she calculate as a critical value for her test? Select one: a. 3.5915 O b. 4.7571 OC.4.7650 d. 3.6823
Please help with the following multiple choice 1. In the one-way ANOVA where there are k treatments and n observations, the degrees of freedom for the F-statistic are equal to, respectively: a. n and k. b. k and n. c. n − k and k − 1. d. k − 1 and n − k. 2. In ANOVA, the F-test is the ratio of two sample variances. In the one-way ANOVA (completely randomized design), the variance used as a numerator...
_____ 5. What statistical test would you use to analyze the data derived from this study? A common belief held by laypersons is that smoking marijuana affects a person’s pupil size. To study this issue, Weil, Zinberg, and Nelson (1968) administered a high dose of marijuana to ten men by having them smoke a potent marijuana cigarette. These men were between the ages of 21 and 26 and all smoked tobacco cigarettes regularly, but had never smoked marijuana. Pupil size...
The ANOVA test is very sensitive to..? Select one: a. changes in sample sizes O b. equal sample sizes c.changes in sample variances d. changes in sample means.
QUESTION 7 The following data are taken from three different populations known to be normally distributed, with equal population variances based on independent simple random samples. Sample 1 Sample 2 Sample 3 39 40 43 37 38 50 35 33 42 45 35 54 37 30 48 30 52 Given that one-way ANOVA was performed and we reject the null hypothesis, please use Tuley's test to determine which pairwise means differ using a familywise error rate of a -0.05. 22...
For a normally distributed variable measured at the interval/ratio level, a 95% confidence level is associated with how many standard deviation units? select one A. depends on the sample size B. depends on the test statistic C.1.96 D. 2.58 If a power analysis indicated that for a given sample size the power was.50, which would be true? select one: A. The risk of a type I error would be a 50% B. The results would be statistically significant 50% of...
please give correct and answer all question.. this is revision question... 14. Which of the following statistical tests is BEST TO normally distributed data? in statistical tests is BEST to use for comparing two samples A. Independent sample t-test B.Mann-Whitney test C. Regression analysis D. Logistic regression analysis 15. Which of the following is NOT related to central limit theoret? sample size is large. bution of sample mean, x is approximately normal regardless of Xin the population 9. The mean...
