[1] Use JMP to construct a histogram and box-plot for the variable Receipt Total. [2] Describe the shape of the distribution. Is the distribution roughly symmetric or skewed in a direction? [3] Does the distribution have any outliers? If so, how many and what are the values? [4] Use JMP to construct a Quantiles table. Paste the quantiles table in the left-hand box and enter the values that make up the five-number summary on the right. maximum 75% quartile median...
Look online to collect some univariate data. For example, you might collect data on the number of HRs hit by the top Major league players, the population for each of the fifty US states, the average SAT scores for all colleges in the Big Ten, or the number of animals at the twenty largest US zoos. Once you do that, please do the following: Discuss where you located your data (website, etc.) (1 point) Organize your data using at least...
The shape of a distribution is a rough guide to whether the mean and standard deviation are a helpful summary of center and variability. Review each of the distributions and determine whether the measures and s would be useful. (a) The figure shows percents of high school graduates in the United States taking the SAT Two peaks suggest that the data include two types of states. 2 20 40 60 80 100 Percent of high school graduates who took the...
please answer all the question 1.1 Data that is recorded on a 1 – 5 rating scale (e.g. 1 = poor, 2 = fair, 3 = good, 4 = very good, 5 = excellent) to a question such as “Rate the level of service you received from your most recent experience with your bank” is: A. nominal data B. continuous data C. interval data D. ratio data E. ordinal data 1.2 A positively skewed histogram means that: A. there are...
Unit 6 Lesson 3 Classwork (Adapted from Math Vision Project) Data Distribution A lot of information can be obtained from looking at data plots and their distributions. It is important when describing data that we use context to communicate the shape, center, and spread. Shape and spread: Modes: uniform (evenly spread- no obvious mode), unimodal (one main peak), bimodal (two main peaks), or multimodal (multiple locations where the data is relatively higher than others). Skewed distribution: when most data is...
Using the column of data HEADLEN, the head length in inches: Construct a frequency distribution by hand with 5 or 6 classes. Sort the data. Identify the minimum and maximum data and the class information: class width, class limits, class boundaries, and class midpoints. Show all work and the resulting frequency distribution table. Hand draw the histogram for the frequency distribution. Make it look professional; title and label appropriately. Use a ruler. Describe the shape of the histogram,...
please I need help with excel or matlab part. part 3 Lab 1 BASIC DATA PROCESSING PRE-LAB ASSIGNMENT 1. Read the lab manual carefully so you know what you have to do when you walk into the lab. 2. In a lab, the resistance of a resistor was measured using 50 samples giving the following values: 119.95 (6), 121.32 (5), 119.57 (7), 117.43(1), 120.76 (15), 120.67 (1), 119.78 (8), 121.43(3), 121.82(1), and 118.47 (3) 2 Estimate the average value of...
1. Consider the (algebraic) constant function f (x) = 1 on the intervalo <x< 20. Is this a PDF? Why or why not? 2. Suppose that follows a continuous probability distribution f (x) = 1 and can take on values between 0 and 10. Explain why P (X = 5) = 0. 3. Sketch a general graph of the 3 continuous PDFs we have discussed so far. How would you describe the shape of each one? (use vocabulary from Chapter...
