A researcher collected data on students’ year in college ranging from Freshman (1) to Senior (4). Using data described in section 2.8 of the textbook (“CollegeYear” data file), please complete the following questions and upload a copy of your output file from JASP or SPSS here.  (a) Create the frequency distribution for the following variable: CollegeYear (b) Indicate the most frequently reported year in college.

The following table contains data on players from the New York Mets’ 2019 season (n=12), including player first name, last name, and number of hits. A hit occurs when a player at bat successfully hits the baseball and makes it to at least first base. Enter these data into JASP or SPSS and use the software to answer the following questions. Make sure to attach a copy of your output file, too! (a) Create a frequency table and calculate the mean, median, and mode for hits. Report your results in writing. (b) Create a histogram and evaluate the shape of the distribution (HINT: make sure to refer to the statistics for skew and kurtosis as the distribution may be visually misleading). Report your findings in writing.

A statistics class has 60% women and 40% men. A researcher selects a sample having 80% men and 20% women. Why should the researcher be cautious of making inferences about the entire class based on the sample?

Which of the following is not a purpose of statistical procedures?

Open JASP or SPSS. Create three variables. Label the variables: ID (for their ID number), Age, Children (for number of children a participant has). Just create the names, no need to define any of the other characteristics today. Then, enter some fictitious data (pretend that you have five participants). Save your dataset. JASP files are saved as .jasp files. SPSS files are saved as .sav files. Attach a copy of your dataset file here.

In a series of experiments, research assistants crouched behind a plastic bag with French fries inside. Then, they waited until a seagull came along. They used a stopwatch to time how long it took the seagull to approach the French fries under two conditions: while the researcher was staring at the seagull, and while the researcher had their head turned away. Every gull experienced both conditions.  Do seagulls take the same amount of time to steal French fries from someone with their head turned as from someone staring at them? Or, is the time it takes to steal the fries different across conditions? Using the data “Gull Stares” from the textbook (also provided on Brightspace), first indicate which t-test should be used to examine this question. Then, conduct the appropriate t-test and report the results of your test using a complete APA write up. Also, report what decision we make about the null hypothesis.
