Research Design and t Tests: How Are They Connected?
For this Discussion, you will critically evaluate a scholarly article related to t tests. To prepare for this Discussion:
Search for and select a quantitative article specific to your discipline and related to t tests. You can use as a guide the Research Design Alignment Table uploaded below.Write a 2-3 paragraph critique of the article. In your critique, include responses to the following:
What is the research design used by the authors?
Why did the authors use this t test?
Do you think it’s the most appropriate choice? Why or why not?
Did the authors display the data?
Do the results stand alone? Why or why not?
Did the authors report effect size? If yes, is this meaningful?
Be sure to support your Main Post and Response Post with reference to Resources and other scholarly evidence in APA Style.Required Readings

We want to collect the Max. Temperature reading for each day in your home city or a city near you in February and August for a minimum of 3years.
Temperature patterns seen to be changing around the U.S. Winters seem shorter,
summers seem hotter, and major storms seem more frequent. Let’s collect some data and
look at what’s happening in your area. You can use the Weather Underground web page
at www.wunderground.com to collect historical data for a particular city. The Weather
Underground (www.wunderground.com) was created by a student/professor team at the
University of Michigan and shortly became a public company providing current and
historical weather data for the United States and other countries. At the top of the
Weather Underground home page you will find a box for entering the name of a city,
state or country. Enter your home city to see the current weather conditions there. Scroll
down and select the History & Almanac Table in which you can enter a date to see
statistics for any day from the past thirty years. Below the field where you enter a specific
date you can select Calender View and see all temperatures for a specific months.We want to collect the Max. Temperature reading for each day in your home city or a city
near you in February (for cold temperatures) and August (for hot temperatures) for a
minimum of 3years.
