Q DATA DAY 1 In this first Data Day assignment, you are going to examine a Data Set called Student Survey. This survey had a lot of information gathered on students in an anonymous school in this county. You will work on a representative (random) sample from that survey. Someone forgot to leave a description of the variables. Today, you are to do two main things: A. Choose three quantitative and 4 categorical variables. Describe each one as thoroughly as you can and tell me what question you think was asked to result in the answers that were given. and B. Use technology to make a graph or table for each of the variables you chose that will, in your opinion, be best able to communicate, to anyone interested, the results of each of the seven survey questions. Your instructor will give you directions at the beginning of class for the following: 1. load excel data into SPSS (or STATCRUNCH or JASP) 2. create simple graphs, including bar graphs, pie charts, and histograms 3. find the mean, mode and median 4. copy information from the results of 3 and paste them into MSWord Save your MSWord document in the following manner: your last name, your first initial, your student ID number, DD1. So, if I am Sue Jones ID 99999999, my document would be saved as joness99999999DD1. Get this information from your instructor. Submit this through BB by 11:59 on Data Day1. If your assignment is not submitted on time, one point will be taken off for each minute late. The lowest possible grade will be zero(0). Your assignment will be graded in the following manner. Followed directions: Proficient: 3 points-- No corrections were necessary; no additional instruction needed Competent: 2 points-- Student understands, did the work appropriately but had some errors/Student demonstrates understanding but needs practice Novice: 1 point-- Student demonstrates lack of understanding/student still learning Not Applicable: 0 points-- Student didn't do this portion of the project. Total possible, 3 points For each variable, Reasonableness of proposed survey questions Proficient: 3 points-- No corrections were necessary; no additional instruction needed Competent: 2 points-- Student understands, did the work appropriately but had some errors/Student demonstrates understanding but needs practice Novice: 1 point-- Student demonstrates lack of understanding/student still learning Not Applicable: 0 points-- Student didn't do this portion of the project. Total possible, 3 points For each variable, Verbal description of variables Proficient: 3 points-- No corrections were necessary; no additional instruction needed Competent: 2 points-- Student understands, did the work appropriately but had some errors/Student demonstrates understanding but needs practice Novice: 1 point-- Student demonstrates lack of understanding/student still learning Not Applicable: 0 points-- Student didn't do this portion of the project. Total possible, 3 points For each variable, Appropriateness of graphs Proficient: 3 points-- No corrections were necessary; no additional instruction needed Competent: 2 points-- Student understands, did the work appropriately but had some errors/Student demonstrates understanding but needs practice Novice: 1 point-- Student demonstrates lack of understanding/student still learning Not Applicable: 0 points-- Student didn't do this portion of the project. Total possible, 3 points For each variable, Appropriateness of numerical summaries Proficient: 3 points-- No corrections were necessary; no additional instruction needed Competent: 2 points-- Student understands, did the work appropriately but had some errors/Student demonstrates understanding but needs practice Novice: 1 point-- Student demonstrates lack of understanding/student still learning Not Applicable: 0 points-- Student didn't do this portion of the project. Total possible, 3 points GRAND TOTAL 15 points No half points will be assigned. This assignment counts as 5% of your total course grade. If you are caught cheating on an exam or a project, you will fail the course and disciplinary charges may be brought against you. ?

First quantitative variable: Height This variable records the height of respondents. As it is quantitative variables, histogram can be used to represent data graphically. Histogram: Shape of height is looking bi-model and almost bell shaped. As the data is for both male and female, two modes can be due to both genders. Descriptive statistics: Summary statistics: Column n Mean Median Mode Height 99 68.30303 68 65 Mean and median are very close to each other, so shape of distribution is not far away from the normal distribution.
