With α = .05, what is the an important t value for a one-tailed test with n = 15?t = 1.761t = 2.145t = 1.753t = 2.131
Under what circumstances have the right to a very small treatment result be statistically significant?If the sample dimension is small and the sample variance is large. If the sample dimension is large and the sample variance is small.If the sample size and the sample variance space both small.If the sample size and the sample variance space both large.

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

Looking at the levels of flexibility value speak you something around _____.the directionality that the theory testthe alpha level the dimension of the samplethe null hypothesis
If other components are held constant, what is the result of enhancing the sample variance?It will certainly decrease the estimated standard error and increase the likelihood that rejecting the null hypothesis. That will rise the approximated standard error and decrease the likelihood the rejecting the null hypothesis.It will certainly decrease the approximated standard error and decrease the likelihood that rejecting the null hypothesis.It will increase the estimated standard error and increase the likelihood of rejecting the null hypothesis.
It will rise the approximated standard error and decrease the likelihood of rejecting the null hypothesis.
With α = .01, the two-tailed vital region because that a t-test using a sample of n = 16 participants would certainly have limits of _____.t = ±2.583t = ±2.602 t = ±2.947t = ±2.921
Which the the complying with is a fundamental difference between the t-statistic and a z-score?The t statistic uses the sample variance in location of the populace variance.The t statistic is supplied for big samples only.The t statistic offers the sample typical in ar of the populace mean.The t statistic computes the conventional error by dividing the standard deviation by n - 1 instead of separating by n.
When n is small (less than 30), exactly how does the form of the t distribution compare to the common distribution?It is taller and also narrower than the normal distribution.It is nearly perfectly normal. The is flatter and more spread out than the common distribution.There is no regular relationship between the t distribution and the typical distribution.
The decision to usage a directional versus non-directional theory test most directly affects _____.the critical value(s)the sample sizethe alpha levelthe levels of freedom
A researcher conducts a theory test making use of a sample indigenous an unknown population. If the t statistic has actually df = 35, how many individuals were in the sample?n = 35 n = 36n = 33n = 34
If other components are organized constant, what is the effect of increasing the sample size?It will certainly decrease the estimated standard error and also decrease the likelihood of rejecting the null hypothesis. It will decrease the approximated standard error and also increase the likelihood that rejecting the null hypothesis.It will rise the approximated standard error and increase the likelihood of rejecting the null hypothesis.It will boost the estimated standard error and also decrease the likelihood of rejecting the null hypothesis.
It will decrease the approximated standard error and also increase the likelihood of rejecting the null hypothesis.
On average, what value is expected for the t-statistic when the null theory is true?0-1.961+1.96
To compute a one-sample t-test a researcher has to know number of values. Which of the complying with is no a worth that the researcher must know to compute this test?The sample varianceThe sample sizeThe estimated standard error The populace variance
Which set of features will produce the smallest worth for the estimated standard error?A big sample size and also a large sample variance.A tiny sample size and also a small sample variance. A huge sample size and a tiny sample variance.A tiny sample size and also a huge sample variance.

If other determinants are hosted constant, just how does sample size influence the likelihood of rejecting the null hypothesis and measures of effect size such as r² and also Cohen"s d?A larger sample reduce both the likelihood and measures of result size.A bigger sample to reduce the likelihood but has tiny influence on procedures of effect size.A bigger sample boosts both the likelihood and also measures of effect size. A larger sample boosts the likelihood however has tiny influence on procedures of impact size.
If you were to _____ the null hypothesis, you would say the an outcome is statistically _____.reject; significantfail come reject; provenreject; nonsignificantfail come reject; significant
