Data which uses numerical values, has an equal distance between points on the scale, and does not have an absolute zero is: Nominal Ordinal Normal Interval
.1. The amount of bivariate data is 2. The smallest value of the independent variable is 3. The largest value of the dependent variable is 4. Pearson's linear correlation coefficient is negative positive
Consider the variable “amount of coffee in a Starbucks Grande coffee”. This variable is best described as: a. A continuous variable measured on the interval scale b. A discrete variable measured on the ordinal scale c. A continuous variable measured on the ratio scale d. A discrete variable measured on the ratio scale
Discuss two data characteristics that could invalidate the use of linear correlation and regression to show the relationship between two ratio scale variables.
A linear regression model predicting the linear effects of the amount of water used in growing almonds is developed below: y = 56+10x The water data has a range of data from 5 to 90 and is in units of 100 gallons, and the almond data is in pounds. According to the model, how many acres will grow if 1000 gallons is used
A divergent color scale would best match which of the following data variables in tableau: data where there is a well-defined midpoint geographical data calendar dates an interval/numeric scale categorical data
Fit a simple linear regression of the form A~B, which is x( independent variable) and which is y(dependent variable) in this case?
It is believed that average grade (based on a four-point scale) should have a positive linear relationship with university entrance exam scores. Given below is the Microsoft Excel output from regressing average grade on university entrance exam scores using a data set of eight randomly chosen students from a large university. Coefficients Standard Error 0.5681 0.9284 1 Stat 0.6119 P-value 0.5630 Lower 95% -1.7036 Upper 95% 2.8398 Intercept University entrance exam score 0.1021 0.0356 2.8633 0.0286 0.0148 0.1895 If we...
Mama's Pizza restaurant chain would like to understand which variable most strongly influences the amount of sales of the deep-dish pizza. They have gathered data on the number of monthly sales (in 100's) of deep-dish pizzas and the amounts month on advertising at 20 of their restaurants. Below are the results of the linear regression to predict the number of month 100's) based on monthly advertising (in $1,000's). SUMMARY OUTPUT - Regression Model to Predict Monthly Sales (in 100's) based...
A person lies on a platform which has a scale under both ends. Imagine the scale on the left reads 535 N and the scale on the right reads 290 N . When the person gets off the platform, both scales read 70.0 N. What is the mass of the person? ________ kg How far from the left hand scale is the center of mass of the person? The length of the platform is L meters. __________ meters
