‘‘The null hypothesis is not rejected’’ (Black

‘‘The null hypothesis cannot be rejected’’ (McDaniel and Gates
2010
, p. 545).

‘‘The null hypothesis … claims that there is no difference between groups’’

(Salkind
2010
, p. 193).

‘‘The difference is not statistically signiﬁcant’’ (McDaniel and Gates
2010

p. 545).

‘‘… the obtained value is not extreme enough for us to say that the difference

between Groups 1 and 2 occurred by anything other than chance’’ (Salkind
2010
,

p. 225).

‘‘If we do not reject the null hypothesis, we conclude that there is not enough

statistical evidence to infer that the alternative (hypothesis) is true’’ (Keller
2009
,

p. 358).

‘‘The research hypothesis is not supported’’ (Zikmund and Babin
2010
, p. 552).

3.3.2 Different Ways to Reject the Null Hypothesis

The following quotes are typical of the quotes used in statistics and research books

when the null hypothesis is rejected:

‘‘The null hypothesis is rejected’’ (McDaniel and Gates
2010
, p. 546).

‘‘If we reject the null hypothesis, we conclude that there is enough statistical

evidence to infer that the alternative hypothesis is true’’ (Keller
2009
, p. 358).

‘‘If the test statistic’s value is inconsistent with the null hypothesis, we reject

the null hypothesis and infer that the alternative hypothesis is true’’ (Keller
2009
,

p. 348).

‘‘Because the observed value … is greater than the critical value …, the

decision is to reject the null hypothesis’’ (Black
2010
, p. 359).

‘‘If the obtained value is more extreme than the critical value, the null

hypothesis cannot be accepted.’’ (Salkind
2010
, p. 243)

‘‘The critical t-value … must be surpassed by the observed t-value if the

hypothesis test is to be statistically signiﬁcant ….’’ (Zikmund and Babin
2010
,

p. 567).

‘‘The calculated test statistic … exceeds the upper boundary and falls into this

rejection region. The null hypothesis is rejected’’ (Weiers
2011
, p. 330).

You should note that all of the above quotes are used by statisticians and

professors when discussing the results of an hypothesis test, and so you should not

be surprised if someone asks you to summarize the results of a statistical test using

a different language than the one we are using in this topic.
