Simple descriptive statistics may be used to depict the sample characteristics, reflecting demographic variable values, in which kind of research?
Ans) Both quantitative and qualitative research
Explaination:
- The term “mixed methods” refers to an emergent methodology of research that advances the systematic integration, or “mixing,” of quantitative and qualitative data within a single investigation or sustained program of inquiry. Collecting and analyzing both quantitative (closed-ended) and qualitative (open-ended) data.

All students who take a statistics course at Brockport are selected to be subjects of a research study. They are asked to fill out a survey including demographic information which is then used to describe the “typical Brockport college student.” What kind of sampling is this? A) convenience sampling B) simple random sampling C) stratified sampling D) cluster sampling
I need to correctly explain descriptive statistics including procedure used, independent sample t- test, ANOVA, and pearson correlation for a 55 sample sleep study. I am not good at statistics at all. can someone help me.

Descriptive statistics like mean, median, range, and standard deviation can be used to summarize data. But the value isn't in knowing how to calculate these numbers, it's in knowing what they mean—or even which ones to consider. This discussion explores that by asking you to take a strictly hypothetical look at a serious circumstance. An article you might want to consider in this context is Stephan Jay Gould’s The Median Isn’t the Message. 1. If you were diagnosed with a...
In statistics, what does df denote? If a simple random sample of 20 speeds of cars on California Highway 405 is to be used to test the claim that the sample values are from a population with a mean greater than the posted speed limit of 65 mi/h, what is the specific value of df? Choose the correct answer below. O A. df denotes the distribution of freedom. For this sample, df 20. O B. df denotes the number of...

3) True or False? If the goal of the study is to understand populations, describe patterns, or ask research questions that are not focused on causality, the best design may be a cross-sectional or cohort study. True False 5) True or False? Case definitions are essential for any outbreak investigation no matter which study approach is used to investigate the epidemic. 6) True or False? Cross-sectional surveys are used to establish baseline data prior to the initiation of longitudinal studies....
A distribution and the observed frequencies of the values of a variable from a simple random sample of the population are provided below. Use the chi-square goodness-of-fit test to decide, at the specified significance level, whether the distribution of the variable differs from the given distribution Distribution: 0.1875, 0.1875, Observed frequencies: 16, 20, 24, 36 Significance level 0.05 0.3125, 0.3125 Determine the null and alternative hypotheses. Choose the correct answer below. OA. H: The distribution of the variable differs from...
