Question 1189991: Refer to the study quoted below: A study (found at http://www.tandfonline.com/doi/abs/10.1080/02702711.2012.739593) employed a convergent mixed-method research design to investigate reading habits of American college students. A total of 1,265 (466 male and 799 female) college students voluntarily participated in the study by completing a self-reported survey. Twelve students participated in semi-structured interviews and classroom observations. Descriptive analysis indicated that the mean hours students spent weekly (M) on academic reading (AR), extracurricular reading (ER), and the Internet (INT), were 7.72 hours, 4.24 hours, and 8.95 hours, respectively.
What is the population, parameter, sample, and statistic in this study? What type of data was collected?

You can put this solution on YOUR website! Here's a breakdown of the population, parameter, sample, statistic, and data type in this study:
* **Population:** All American college students. This is the larger group the researchers want to draw conclusions about.
* **Parameter:** The true mean hours spent weekly on academic reading, extracurricular reading, and the internet *for all American college students*. These are the values the researchers would ideally like to know but can only estimate. We don't know the true population parameters.
* **Sample:** The 1,265 college students who voluntarily participated in the study by completing the survey. This is the subset of the population that was actually studied.
* **Statistic:** The mean hours spent weekly on academic reading (7.72 hours), extracurricular reading (4.24 hours), and the internet (8.95 hours) *for the sample of 1,265 students*. These are the values calculated from the sample data and used to estimate the population parameters.
* **Data Type:** The study collected both quantitative and qualitative data.
* **Quantitative Data:** The number of hours spent on academic reading, extracurricular reading, and the internet are numerical measurements, making this quantitative data. Specifically, it is *continuous* quantitative data, as the hours can take on a range of values (e.g., 7.72 hours, not just whole numbers).
* **Qualitative Data:** The information gathered from the semi-structured interviews and classroom observations is qualitative data. This type of data is descriptive and non-numerical, often focusing on experiences, perspectives, or themes.
