residual The difference between the observed value of the dependent variable and the value predicted using the estimated regression equation is called a(n) increase the value of the correlation. Influential observations always: normal probability plot. A graph of the standardized re...

stratified random sampling A form of probability sampling; a random sampling technique in which the researcher identifies particular demographic categories of interest and then randomly selects individuals within each category. Parameter A numerical characteristic of a population, such as a...

IMPORTANT PRACTICE TEST INFORMATION!!!! This may be even more helpful than this quizlet!!!! In mindtap go to the left-hand toolbar, select courses, and select this course. You should see a dashboard with the chapters on the left and your recent homework scores on the right. Then on chapter 1 c...

Discrete Data Values are whole numbers (integers) -Usually counted, not measured Continuous Data Can potentially take on any value, depending only on the ability to measure accurately -Often measured, fractional values are possible Discrete Random Variables have outcomes that typi...

Analytics is the scientific process of transforming data for decision making. There are three broad areas of data analytics. Descriptive Analytics which describes what has happened in the past. Predictive Analytics uses statistical models from past data to predict the future [foreca...

What is a sample space the set of all possible outcomes outcome is the result of the experiment What is a trial Repetitionfrom a random experiment Random experiment Has outcomesthat we cannot predict Experiments involvechanceor random results Probability Refers to a numb...

If the confidence interval for the regression slope includes​ zero, we would have some evidence that beta could be equal to​ zero, which would indicate that there may not be a relationship between the dependent and independent variables. True A professor would like to test the hypothesi...

A survey of 800 college seniors resulted in the following crosstabulation regarding their undergraduate major and their plan of going to graduate school. According to the crosstabulation above, what percent of undergraduate majors plan to go to graduate school? 65.0% 19.3% 27.8% 35.0% 35.0% ...

The difference between the actual time series value and the forecast is called: forecast error. In the linear trend equation, Tt = b0 + b1t, b0 represents the: y- intercept of the trend line. The time series model that is appropriate in situations where the seasonal fluctuations do n...

Mean average value for a variable Sample Mean denoted as

Complement of Event A all the sample points not in the event Union of Two Events -event containing all sample points belonging to Event A, Event B or both -denoted by

Addition law A probability law used to compute the probability of the union of two events. It is P(A ∩ B) = P(A) + P(B) − P(A ∪ B). For mutually exclusive events, P(A ∩ B) = 0; in this case the addition law reduces to P(A ∪ B) = P(A) + P(B). Basic requirements for assigning pro...

Suppose a political party wants to estimate how favorable a certain candidate is to state voters. To do so, a sample of 400 registered voters were selected. Suppose 160 found the candidate "favorable". An estimate of the proportion of the population of registered voters is 160/400=40%. This is an ...
