1)
Level of measurement of a dependent variable in binomial logistic regression is,
Dichotomous
Reason : the binomial logistic regression is where the input is classified into one of the 2 outcome of the output. Therefore it is dichotomous.
2.
Level of measurement of a independent variable in a binomial logistic regression is,
Independent variables can be nominal only.

In difference of means tests, the dependent variable is typically of what level of measurement? A. nominal B. ordinal C. interval/ratio D. any of the above
1. Changing the unit of measurement of dependent variable, where log of the dependent variable appears in the regression: a. affects only the slope coefficient. b. affects neither the slope nor the intercept coefficient. c. affects only the intercept coefficient. d. affects both the slope and intercept coefficients. 2. Which of the following statements is true when the dependent variable, y > 0? a. Taking log of variables make OLS estimates more sensitive to extreme values. b. Models using log(y)...

1. Since researchers cannot always conduct true experiments, one must control spurious relationships. True or False 2. To use multiple regression equation the dependent variables and all of the independent variables have to be measured at the interval or ratio level. True or False
The Correctional facility that you work is considering using a new program designed to improve the pro-social attitudes of violent offenders. This program, based on a cognitive intervention strategy, involves a six week series of lessons whereby the inmates are given real world scenarios and asked to make decisions on how to handle them. Prior to the start of the program the inmates are to be given a survey type inventory and asked whether they agree or disagree with various...

They used 25 baby rats to do the study, and each of them was measured under three different soy percentages (1%, 3.5%, and 5%) What statistical test should they use to test if there is a diference among the average effect of different percentages of...
A valid multiple regression analysis assumes or requires that Select one: O a. The dependent variable is measured using an ordinal, interval, or ratio scale O b. The residuals follow an F distribution O c. The independent variables and the dependent variable have a linear relationship O d. The observations are autocorrelated
3. Levels of Measurement. Identify the level of measurement of the following variables (nominal, ordinal, interval, ratio) (pay attention to how these variables are operationalized) (16 points) 1. Respondents were asked to select a category from a list of three. 2. Respondents were watched during daily activities and were ranked from 1-8 on their level of honesty where 1 = very dishonest and 8 = very honest. 3. Social Class. Respondents were asked to determine their family's financial situation on...
Given exam scores: 105,91,52,86,100,96,98,109,96,103,84. 1) What is the sample size? 2) Qualitative, quantitative or neither? 3) Discrete, continuous or neither? 4) Which is the level of measurement: nominal, ordinal, interval or ratio?
Survey responses of 'yes."no,"and "no opinion" OA. The interval level of measurement is most appropiate because the data can be ordered, differences (obtained by subtraction) can be found and are meaningful, and there is no natural starting poirt Ο B. The rdnal level of measurements most approprate because the data can be ordered but dferences (ottaned by subtracton) canot be fund or are meanngless O C. The nominal level of measurement is most appropriate because the data cannot be ordered...
