Submit a short and broad description of prevalence of gambling in Australia. You should draw information/evidence from the academic literature, government sources, and statistics from ABS or other authorities. No web sources should be used. You should focus on and address the following questions: How many/What percentage of Australian adults engaged in gambling in 2015? Are these numbers high compared to some other countries? Do Indigenous Australians gamble more often than non-Indigenous Australians? Are your sample statistics comparable with the findings from those in the literature? If not, cite the main reasons (hint: you should pay attention to who are in your sample). Other requirements: The description should be no more than one-page (excluding the reference list) with a font size not less than Calibri 11. All sources should be properly cited and referenced.

A power analysis is a calculation used to estimate the smallest sample size needed for an experiment, given a required significance level, statistical power, and effect size. It helps to determine if a result from an experiment or survey is due to chance, or if it is genuine and significant. Think of an experiment or a survey that you have conducted or will conduct in your field of interest and use it to discuss the following questions: 1. Describe the importance of power analysis in an experiment. 2. How will you determine the appropriate significance level for a power analysis? 3. Explain, in your own words, how you will conduct a power analysis in your experiment or survey.
