1.The survey data STATISTICSSTUDENTSSURVEYSAV contains several columns. Identify the type of variable in the column FEDBEST, a variable that measures which federal political party students think has the best platform (Conservative, Green, Liberal, NDP). qualitative categorical (ordinal) quantitative numerical discrete qualitative categorical (non-ordinal) quantitative numerical continuous 2.The survey data STATISTICSSTUDENTSSURVEYSAV contains the column FAAGESTUDBIRTH which is a variable that measures the age of students' fathers when students were born. Use SPSS to make a histogram to describe the data. Choose the most correct answer to describe what you see in the shape of the data distribution. right skewed uniform left skewed Symmetric Graphs > Legacy Dialogs>Histogram Variable: FAAGESTUDBIRTH OK

3.The Excel file STATISTICSSTUDENTSSURVEYSAV contains the column BEFPULSEMIN (a numerical variable that measures student pulses before completing an online survey) and the column BEFBREATHMIN (a numerical variable that measures student breaths per minute before completing an online survey). For education purposes, consider this dataset to be a sample of size 60 taken from a much larger population for statistics students. Consider BEFPULSEMIN to be a response variable and BEFBREATHMIN to be an explanatory variable. Choose the most correct answer below The line of best fit for this data is BEFPULSEMIN = 46.186 + 1.51BEFBREATHMIN and the correlation between the variables is 0.685 The line of best fit for this data is BEFPULSEMIN = 46.186 + 1.51BEFBREATHMIN and the correlation between the variables is 0.828. The line of best fit for this data is BEFBREATHMIN = -15.070 + 0.454BEFPULSEMIN and the correlation between the variables is 0.828. The line of best fit for this data is BEFBREATHMIN = -15.070 + 0.454BEFPULSEMIN and the correlation between the variables is 0.685. Analyze > Regression > Linear Dependent: BEFPULSEMIN Block 1 of 1: BEFBREATHMIN, OK 4.Randomly collected student data in the dataset STATISTICSSTUDENTSSURVEYSAV contains the columns FEDVOTE(voted Federal party (Conservative, Green, Liberals, or NDP) ). Make a frequency distribution for the variable FEDVOTE. What is the probability a randomly selected student votes Federal NDP? Choose the most correct (closest) answer below. 0.217 0.500 0.450 0.283 Analyze > Descriptive Statistics > Frequencies Variable: FEDVOTE, OK

5.The Excel file STATISTICSSTUDENTSSURVEYSAV contains the column FEDBEST, a variable that measures which federal political party students think Ha d the best platform (Conservative, Green, Liberal, NDP) and the column FAVSEASON, a variable that measures students favourite season (Spring, Summer, Fall, Winter). Create a cluster bar chart to illustrate the relationship between FEDBEST and FAVSEASON. Choices for FEDBEST should add to 100% within each of the four choices for FAVSEASON. Within the cluster for Spring, what percent of students view Liberals as best? 10.00% 25.00% 37.50% 35.29% Graphs> Chart Builder, OK Double Click on Icon for Side by Side Clusters Move FAVSEASON to the X axis Move FEDBEST to the “Cluster on X” legend Under Elements Propertites tab, go to Statistics dropdown and choose Percentage Click “Set Parameters” In “Element Properties Set Parameters” pop up box, choose “Total for Each X Axis Category”, Continue OK Click on graph to Bring up Chart Editor Right click on a bar and select “Show data labels” OK

6.The survey data STATISTICSSTUDENTSSURVEYSAV contains the column ENDPULSEMIN (a variable that measures student pulse in beats per min (bpm) after doing the survey) and the column UNDERGORGRAD (a variable that measures whether the student is pursuing an undergraduate or graduate degree). Use SPSS to find the mean and standard deviation of student pulse rate in beats per minute for the undergrad students and the mean and standard deviation of student pulse rate in beats per minute for the graduate students. Choose the most correct answer below. The undergraduate mean is less than the graduate mean and the undergraduate standard deviation is less than the graduate standard deviation. The undergraduate mean is more than the graduate mean and the undergraduate standard deviation is less than the graduate standard deviation. The undergraduate mean is less than the graduate mean and the undergraduate standard deviation is more than the graduate standard deviation. The undergraduate mean is more than the graduate mean and the undergraduate standard deviation is more than the graduate standard deviation.
