With α = .05, what is the important t value for a one-tailed test through n = 15?t = 1.761t = 2.145t = 1.753t = 2.131
Under what scenarios can an extremely tiny treatment impact be statistically significant?If the sample dimension is little and the sample variance is huge. If the sample size is massive and the sample variance is small.If the sample size and the sample variance are both tiny.If the sample dimension and also the sample variance are both huge.

You are watching: Under what circumstances can a very small treatment effect still be significant

Looking at the levels of liberty worth tells you somepoint about _____.the directionality of the hypothesis testthe alpha level the dimension of the samplethe null hypothesis
If other components are held consistent, what is the effect of increasing the sample variance?It will certainly decrease the estimated traditional error and boost the likelihood of rejecting the null hypothesis. It will boost the estimated traditional error and decrease the likelihood of rejecting the null hypothesis.It will certainly decrease the approximated conventional error and also decrease the likelihood of rejecting the null hypothesis.It will increase the approximated conventional error and also rise the likelihood of rejecting the null hypothesis.
It will rise the approximated traditional error and also decrease the likelihood of rejecting the null hypothesis.
With α = .01, the two-tailed critical region for a t-test using a sample of n = 16 participants would certainly have boundaries of _____.t = ±2.583t = ±2.602 t = ±2.947t = ±2.921
Which of the adhering to is a standard difference between the t-statistic and also a z-score?The t statistic supplies the sample variance in area of the populace variance.The t statistic is provided for huge samples just.The t statistic offers the sample mean in area of the population intend.The t statistic computes the conventional error by separating the standard deviation by n - 1 instead of dividing by n.
When n is tiny (less than 30), how does the shape of the t circulation compare to the normal distribution?It is taller and narrower than the normal distribution.It is nearly perfectly normal. It is flast and even more spcheck out out than the normal distribution.Tright here is no constant relationship in between the t distribution and also the normal distribution.
The decision to usage a directional versus non-directional hypothesis test most directly affects _____.the critical value(s)the sample sizethe alpha levelthe levels of freedom
A researcher conducts a hypothesis test making use of a sample from an unrecognized population. If the t statistic has df = 35, just how many people were in the sample?n = 35 n = 36n = 33n = 34
If other factors are hosted continuous, what is the impact of boosting the sample size?It will certainly decrease the estimated traditional error and also decrease the likelihood of rejecting the null hypothesis. It will decrease the estimated standard error and increase the likelihood of rejecting the null hypothesis.It will rise the estimated typical error and boost the likelihood of rejecting the null hypothesis.It will boost the approximated typical error and decrease the likelihood of rejecting the null hypothesis.
It will certainly decrease the approximated conventional error and also boost the likelihood of rejecting the null hypothesis.
On average, what value is expected for the t-statistic once the null hypothesis is true?0-1.961+1.96
To compute a one-sample t-test a researcher has to recognize a number of worths. Which of the following is NOT a worth that the researcher have to know to compute this test?The sample varianceThe sample sizeThe approximated standard error The populace variance
Which collection of attributes will certainly create the smallest value for the estimated conventional error?A large sample size and also a large sample variance.A little sample size and a small sample variance. A huge sample size and also a little sample variance.A tiny sample size and also a huge sample variance.

If other factors are hosted constant, exactly how does sample dimension affect the likelihood of rejecting the null hypothesis and measures of effect dimension such as r² and also Cohen"s d?A larger sample decreases both the likelihood and procedures of result size.A larger sample decreases the likelihood but has actually bit affect on measures of impact dimension.A larger sample rises both the likelihood and also procedures of effect size. A larger sample increases the likelihood however has little affect on measures of effect dimension.
If you were to _____ the null hypothesis, you would say the result is statistically _____.reject; significantfail to reject; provenreject; nonsignificantfail to reject; significant
