. What is the difference between univariate data and bivariate data? Choose the correct answer below A. In unhanate data, there is one mean. In bivariate data, there are two means B. In unvanate data, there are only postive values and zeros in bivanate data, there re postre values, negative vallues, and zeros C. In univariate data, the data are qualitative. In bivariate data, the data are quantitative. D. In univariate data, a single variable is measured on each individual. In bivariate data, two variables are measured on each individual. 2. Fill in the blank below If r=-1 then a perfect negative linear relation exists between the two quanttative variables. t then a perfect negative linear relation exists between the two quantitative variables (1) O 0, O 2, 0 1, 3. True or false: Correlation implies causation Choose the correct response False O True Determine whether the scatter diagram indicates that a inear relation may exist between the two vanables. If the relation is linear, determine whether it indicates a positive or negative association between the variables. Use this information to answer the following. 4. 400-···· 300- 10 Explanatory Do the two variables have a linear relationship? O A. The data points do not have a linear The data ports have a linear relationship because they do not lie mainly in a straight line O B. relationship because they do not lie mainly in a straight line O C. The data points have a linear relationship OD. The data points do not have a linear relationship because they lie mainly io a straight line. because they lie mainly in a straight line If the relationship is linear do the variables have a positive or negative association? 0 A. The variables have a negative assocation. O B. The variables have a positive association. ° C. The relationship is not linear. 2/27/2018 ttps://xlitemprod.pearsoncmg.com/api/v1/print/mathExplanation / Answer
1. Univariate means "one variable" (one type of data)
Example: Travel Time (minutes): 15, 29, 8, 42, 35, 21, 18, 42, 26
The variable is Travel Time
Bivariate means "two variables", in other words there are two types of data
Example:
An ice cream shop keeps track of how much ice cream they sell versus the temperature on that day.
The two variables are Ice Cream Sales and Temperature.
Hence answer is D.
