1. What type of study is your research article (qualitative or quantitative)?
- The article , “Changes in young adults’ alcohol and marijuana use, norms, and motives
from before to during the COVID-19 pandemic” is quantitative study. Because is about
study of young adults (N=572; Mage=25.14; 60.8% women) that was recruited in
Washington State that used alcohol and marijuana, norms and motives from 2015 to
2016 sample and the method is representing with repeated-measures design, data that
were collected before COVID-19 January 2020 that was pre pandemic and April/May
2020 first phase of pandemic time.

research design?
- The section of the research journal article that describes the number of subjects and
the research design is the Method Section, Methods describes the data collection and
analysis procedures for a research project, and in this article is a study about
collecting data from2015 to 2016 and comparing with pre-pandemic January 2020
and during the initial phase of the pandemic to April/May 2020, and comparing with
same sample of surveyor.
3. If you do not have time to read an entire research article, which section would you read to
review the purpose of the study, the description of the subjects, and the data analysis and
important findings?
- If you do not have time to read an entire research article, you read first Abstract.
Abstract summarizes the entire article, also, helps to find out if we should read all
article or not. Most journal articles have abstract that is free, and you can find out if
this journal article is one you need and have information for your research or not. In
this article the Abstract have all information and I need to know for this research
article about alcohol and marijuana use in young adults, and how they conduct the

4. What does p= define in the research paper? Why is this important?
- The p-value provide information on the probability of the observations, for given
statistical model research when the null hypothesis is true. p value of 0.5 suggests that
there is a 50-50 chance that the findings of the study are significant. A p value of 0.05
(the value customarily used to suggest that research results are statistically
significant) means that there is a 5% chance that the results of the study occurred by
chance alone p value of 0.5 suggests that there is a 50-50 chance that the findings of
the study are significant. A p value of 0.05 (the value customarily used to suggest that
research results are statistically significant) means that there is a 5% chance that the
results of the study occurred by chance alone
The p= value is important because is the preference method to summarize the results
of medical articles, that p=value is outcome of a statistical test and is important
summary for statistical analyses.
5. What n= define in the research paper?
- n= is sample size that refers to the number of participants or observations sample. In
this article there were 572 participants (N=572; Mage=25.14; 60.8% women)
6. What is the Dependent Variable in the research paper?
- In the research paper the Dependent Variable is the variable that depends on other
factors that are measured, or the variables that is being studied. In this article, the
dependent variable are the alcohol and marijuana use, that the research is based on.
