You capture data by having 8 people fill in 30 small dots on a piece of paper and you time them,one time using their left hand and the second time using their right hand. So for each of the eight individuals you have two times. You compile this data in a table including the persons name and if they are right or left handed. How would you create a scatterplot with this data with the x axis being the column of the explanatory variable and the y-axis being the response variable?
Response variable would be a result of comparing the Left hand time and Right hand time .
Y axis can be response variable Left and Right or 0, 1
X axis can be the difference of times between X axis and Y axis

Homework 4 Use the hand span data that we collected in class for homework Suppose you want to buy someone a pair of love, but you do not know their love size. Usually, we do have a pretty good idea of the person's height. Let' asume that the right hand span is a rood indicator of the love size. So let find the best predictor of right hand span be on the person's height. Once we can predict the right...
i have this project on statistics and I dont know how to go about it. i sm to pick a topic and it was going to be Age and dementia. please can someone help as i am so frustrated already. In some cases, the relationship between the two variables is a linear one. In this project, you will need to choose a pair of real-world variables, collect data on those variables, and describe the relationship between the variables. To complete...
Several students were tested for reaction times (in thousandths of a second) using their right and left hands. (Each value is the elapsed time between the release of a strip of paper and the instant that it is caught by the subject.) Results from five of the students are included in the graph to the right. Use a 0.10 significance level to test the claim that there is no difference between the reaction times of the right and left hands....
USE R STUDIO The stackloss data frame available in R contains 21 observations on four variables taken at a factory where ammonia is converted to nitric acid. The first three variables are Air.Flow, Water.Temp, and Acid.Conc. The fourth variable is stack.loss, which measures the amount of ammonia that escapes before being absorbed. Read the help file for more information about this data frame. - Give a numerical summarization of each column of the dataset, then use boxplots to help illustrating...
You are required to write a program to draw dots using the data # given in the variable coords_list below. The variable coords_list # contains a list of (x, y) coordinate pairs. Each (x, y) pair # specifies a position on the screen. # # Write a program to draw dots at the positions in the list. # All the dots are to be of the size defined in the variable supplied. # If x in a pair (x, y)...
Please help guide or explain how I would graph this? Thank you
so much
IV. Data Table • Fill in the remaining columns on your data table. Calculate the solubility at each temperature by dividing the mass of KNO, used by the volume of solution at that temperature. (Watch sig tig! V. Graphing the data - Temperature (°C) on the x-axis and Solubility (g KNO/mL solution) on the y-axis • Orient graph paper as noted "up" with long dimension on...

Data was collected in order to investigate the effect of temperature on the yield of a chemical process. Temperatures were set at eight specific levels, and the yield was determined for five replications at each evel 4. a. Identify the response variable and the predictor variable. Explain your reasoning b. Describe the two sources of variation (variation due to regression and variation about the regression) in terms of this particular problem...
TEST 1: ANSWERS INTS EACH). This section takes around 5 minutes. Name Spring 2019 8) A researcher wants to determine whether female teachers give higher or lower grades, on average, then male teachers. She picks a random sample by picking a random sample of schools, in the schools picked, picking a random sample of departments, and in the departments picked, picking a random sample of teachers. What kind of sampling was performed? d) voluntary response e) cluster b) stratified Random...
Problem 4: Variables that may affect Grades The data set contains a random sample of STAT 250 Final Exam Scores out of 80 points. For each individual sampled, the time (in hours per week) that the student spent participating in a GMU club or sport and working for pay outside of GMU was recorded. Values of 0 indicate the students either does not participate in a club or sport or does not work a job for pay. The goal of...
Data For Tasks 1-8, consider the following data: 7.2, 1.2, 1.8, 2.8, 18, -1.9, -0.1, -1.5, 13.0, 3.2, -1.1, 7.0, 0.5, 3.9, 2.1, 4.1, 6.5 In Tasks 1-8 you are asked to conduct some computations regarding this data. The computation should be carried out manually. All the steps that go into the computation should be presented and explained. (You may use R in order to verify your computation, but not as a substitute for conducting the manual computations.) A Random...
