Frequency distributions can be created for _____________.
| both numerical and categorical variables |
| only numerical variables |
| neither numerical nor categorical variables |
| only categorical variables |
We can create frequency distribution for both categorical and nunerical variables. For example, we can create frequency distribution for number of males and females in a class which is categorical. Also, we can create frequency distribution for the number appeared in rolling a die for 1000 times.
So, (a) should be the correct answer.
Frequency distributions can be created for _____________. both numerical and categorical variables only numerical variables neither...
Question 11. For each of the following variables, indicate whether they are categorical or numerical. Also, write down what type of graph can be drawn for each. Civil status of participants. Height of participants.
For each of the following variables, determine whether the variable is categorical or numerical. If the variable is numerical, determine whether the variable is discrete or continuous. In addition, determine the measurement scale. a. Number of trips taken to the mall in the past week b. Least favorite holiday c. Amount of time spent shopping for clothing in the past week d. Most likely time period during which shopping for clothing takes place (weekday, weeknight, or weekend) a. Number of...
Question 5 Paired occurrences are displayed in frequency distributions. a. True b. False Question 6 This statistical feature distinguishes histograms from bar charts a. They have more than 1 category (bar) b. There is no ‘0’ value c. Data must be continuous d. Outliers are excluded This graphical display of data is best suited for longitudinal data (to show changes over time) a. Bar chart b. Histogram c. Scatterplot d. Line chart Question 8 Dependent variables are usually placed on...
Frequency distributions can be formed from which of the following types of data? Both discrete and continuous Discrete only Continuous only Only qualitative data
A. To examine relationships between a categorical and a numerical variable, we can use a. counts and corresponding charts of the counts b. scatterplots c. correlation matrices d. box-whisker plots B. Coding all Business majors as 1 and all others as 0 in a data set illustrates the use of a. numerical variables b. dummy variables c. ordinal variables d. nominal variables C. Abby has been keeping track of what she spends on Starbucks coffee. The last seven week's expenditures,...

The Law of Conservation of Energy insists that energy can neither be created nor destroyed. Is there any hope for us to create energy on earth with available resources? What is Dark Energy? How does it fall into the category of energy creation? Not meaning transformation.
Ungrouped qualitative frequency distributions and grouped qualitative frequency distributions both have their pros and cons. Choose a healthcare research topic that interests you and provide examples of when it would make more sense to use ungrouped vs. grouped, and vice versa. Explain all your answers in detail.
The first law of thermodynamics states that energy can neither be created nor destroyed. How then is it possible for ∆E to be anything other than zero? In other words, what do we mean when we call a physical scenario “non-conservative” if energy must, by nature, be conserved?
