You will submit one Word document for this assignment. You will create this Word document by cutting and pasting SPSS output into Word and naming the file johnsoncPSY7107-5.doc Begin by downloading the following SPSS data sets:Downloadfestival.savChickflick.savHiccups.savTextmessages.savExamAnxiety.savPart A. Creating Visual Displays of Data. For this assignment, you will copy and paste output you created while working in Chapter 4 into a Word document. Please read the instructions below to ensure you are pasting the correct material into your assignment (This chapter has you create many charts and not all are required for this assignment).Using the data set: DownloadFestival.sav, calculate the mean, standard deviation, and minimum and maximum values for the variable Day1. You should notice that there is an outlier for this variable and you should change the value of the outlier you have identified to 2.02. Next, you will create a boxplot for males and females for the Day1 variable. Be sure to save the data set with a new name, indicating it is the corrected data set (outlier identified and corrected). Save this boxplot, with an appropriate title in your assignment document. Using the data set: Chick-Flick.sav, create a simple bar chart for independent means. The variables you will use are: Arousal, Film, and Gender (grouping variable). Be sure to display error bars and save your chart with an appropriate title in your assignment document.Using the data set: Hiccups.sav, create a bar chart for related means. The variables you will use are: Baseline, Tongue Pulling, Carotid Artery Massage, Digital Rectal Massage. Be sure to display error bars, include labels for the X- and Y-axis, and save your chart with an appropriate title in your assignment document.Using the data set: Text Messages.sav (note: you may see an additional data set with the same name: TextMessages.sav – either will create the correct output), create a clustered bar chart for mixed designs. The variables you will use are: Time1, Time2, and Group. Be sure to display error bars, include labels for the X- and Y-axis, and save your chart with an appropriate title in your assignment document.Using the data set: Exam Anxiety.sav, create a scatterplot that includes a regression line. The variables you will use are: Exam Performance and Exam Anxiety. Be sure to include the regression line and save your chart with an appropriate title in your assignment document.Part B. Why Exploratory Data Analysis? Write a short paragraph that highlights your understanding of why exploratory data analysis is a critical part of any analytical strategy (300-500 words). You should support your answer to this question by citing and referencing the course materials or other scholarly resources. This answer is worth 5 points (half the assigned points for this assignment). To receive full credit you must show a high level of understanding the importance of exploring data visually.

Southern New Hampshire Direct Proofs in Natural Deduction Project
Choose two of the arguments below and write a direct proof using the eight rules of inference introduced in section 8.1 of the textbook. You can do argument 1 or argument 2, but not both, then any of arguments 3–6. Note that commas are used to separate the premises from each other.1. ~M, (~M • ~N) → (Q → P), P → R, ~N, therefore, Q → R2. ~F → ~G, P → ~Q, ~F v P, (~G v ~Q) → (L • M), therefore, L3. ~(Z v Y) → ~W, ~U → ~(Z v Y), (~U → ~W) → (T → S), S → (R v P), [T → (RvP)] → [(~R v K) • ~K], therefore, ~K4.

(C → Q) • (~L → ~R), (S → C) • (~N → ~L), ~Q • J, ~Q → (S v ~N), therefore, ~RNatural deduction is so called because it is a model for how we naturally reason. This often comes as a surprise to students because all of the symbols seem anything but natural. The symbols, however, allow us to focus on the form of the argument without getting bogged down by content. Recall that each sentence letter represents a simple sentence in English.After writing your direct proofs, construct a translation key for your argument by assigning each letter a simple sentence, and use that key to fill in the content of the argument.

Did the data handlers do a good job in constructing a quality statistical picture? Examine the statistical picture below and if you see a feature that is problematic (e.g., inaccurate or misleading), place your cursor over that feature and click. If you change your mind, click on the clear button on the bottom left and you can begin again. If you decide the statistical picture contains no problematic features, click just above the word "cheese." (Hint: Check out the components of a well-designed statistical picture that are listed on page 7 of the Module 6 course notes, such as appropriate Title, correct Source, etc.)

In a study of binge drinking among undergraduates at Ohio University, a researcher was interested in gender differences as related to binge drinking and to drinking-related arrests. She wanted to know two things: (a) Is there a significant relationship between gender and binge drinking (as defined by 5 or more drinks at one sitting), and (b) Is there a significant relationship between gender and drinking-related arrests? A random sample of males and females were asked about their experiences with binge drinking and with drinking-related arrests. Test for a relationship in the following data:
Use the numbers below for this question only!
Experience Alcohol-related Arrest?
YES NO
Male 35 23
Female 20 50
What is the calculated chi-squared value?
Question 14
Using a critical value of 3.84, and based on the obtained chi-square value in Question 13, is there a significant relationship between gender and alcohol-related arrests?
Yes
No
Question 15
Which of the following shows relationships between measurement variables?
Bar graph
Line graph
Pie chart
Pictogram
Scatterplot
Question 16
Papa Johns conducted a survey of 100 nursing students taking statistics to determine what toppings they preferred on their pizza. Data handlers converted students' responses into a pie (no pun intended) chart to display the results clearly to upper management. Did the data handlers do a good job in constructing a quality statistical picture? Examine the statistical picture below and if you see a feature that is problematic (e.g., inaccurate or misleading), place your cursor over that feature and click. If you change your mind, click on the clear button on the bottom left and you can begin again. If you decide the statistical picture contains no problematic features, click just above the word "cheese." (Hint: Check out the components of a well-designed statistical picture that are listed on page 7 of the Module 6 course notes, such as appropriate Title, correct Source, etc.)

Which of the following is not a true statement about bar graphs?

Bar graphs represent categorical data.
Pictograms are similar to bar graphs except they use pictures related to the topic.
