I need a research hypothesis for RES/341 that explains three possible outcomes that may result from the following research question: "What was the median cost of a single family house in the state of Minnesota in 2005 compared to the cost of a single family house in 2010."I also need to identify the variables to be tested, define the level of measurement for each variable, and define the measurement scale for each variable. Additionally, I am required to briefly discuss the remaining steps in the research process. These remaining steps must include a review of literature, sampling design, data collection, data analysis using descriptive statistics, and conclusions. More than one question indeed!
