You’ll be asked to convert a word problem into ahypothesisstatement in statistics that will include a null hypothesis and analternate hypothesis. Breaking your problem into a few small steps makes these problems much easier to handle. How to State the Null Hypothesis Example Problem: A researche...
How do I State the Null Hypothesis? You won’t be required to actually perform a real experiment or survey in elementary statistics (or even disprove a fact like “Pluto is a planet”!), so you’ll be given word problems from real-life situations. You’ll need to figure out what your...
Of course, not all studies have hypotheses (there is also exploratory or hypothesis-generating research), and you do not necessarily have to state your hypothesis as such in your paper. But for the sake of understanding the principles of the scientific method, let’s first take a closer ...
We investigate this question in the context of the COVID-19 pandemic: How people make sense of, and judge,vaccination-contingent behaviors—behaviors, such as going to the gym or a bar, which are considered to be more or less risky and appropriate, depending on the target’s vaccination sta...
When assessing m1.5, the null hypothesis is that the instruments are valid instruments, i.e., they are uncorrelated with the error term and cannot be rejected at a satisfactory level of significance. Focusing on the m1.5 variation of the m1 model, it is possible to express the relationship ...
To this end, Hypothesis 1 is proposed: Hypothesis 1 (H1). Spatial injustice leads to the unobvious decrease in residents’ policy acceptance of the economic objectives of CLR, leading to an obvious decrease in residents’ policy acceptance of social and ecological objectives of CLR. In other wo...

(p = 0.041), which leads us to reject the null hypothesis of this test that humility was normally distributed. Listwise deletion was used to handle missing data, yielding a final sample size of 1152. Results were also consistent if multiple imputation with chained equations was used to ...
Because nonparametric tests are less powerful, how does this impact decisions about the null hypothesis? If the significance level that you obtain for Levene's Test for Equality of Variances equals 0.013, what should you do? a) This would not ...
A two-sample Kolmogorov-Smirnov test rejects the null hypothesis that learning-time losses do not differ by student achievement (p = 0.014). Thus, average differences in learning-time losses as reported in Table 1 are not driven by extreme outliers but are rather observable throughout the ...
