pops the most popcorn kernels. Which among the choices is the independent variable? -
✔✔b. Brand of popcorn bags
Nominal scale is _______________________ in nature, which means numbers are used here
only to categorize or identify objects. - ✔✔Qualitative
The central tendency of the ordinal scale is _______________________________. -
✔✔Median
Compute the frequency of all nominal variables using what formula? - ✔✔c. =COUNTIF()
It is a nominal level variable that can take only two values (yes/no, male/female,
Hungarian/non-Hungarian). - ✔✔d. Dichotomy
It is often based on statements of statistical significance and probability. - ✔✔d. Modern
science
Sex or Gender is classified under what level of measurement? - ✔✔Nominal
It is the outcome variable measured in each subject, which may be influenced by manipulation
of what variable? - ✔✔Independent
Using a ratio scale permits comparisons such as being twice as high, or one-half as much. -
✔✔True
,By default, all variables fall in one of the four scales. - ✔✔True
Age is under what level of measurements? - ✔✔Interval
Although in an interval scale, since there is an absence of the absolute 0 and it works on the
principal of an arbitrary 0, the division of variables is not possible. - ✔✔True
Classify the level of measurement it belongs: Score in IQ Test - ✔✔b. Interval
It is used as a comparison parameter to understand whether the variables are greater or lesser
than one another using sorting. - ✔✔Ordinal
It refers to the relationship among the values that are assigned to the attributes for a variable. -
✔✔a. Levels of Measurement
The measures of central tendency are mean, median and mode. - ✔✔True
Which is classified as Ratio? - ✔✔Sibling
It is the scientific study of earthquakes. - ✔✔d. Seismology
It is a branch of science that deals with the collection, organization, analysis of data and
drawing of inferences from the samples to the whole population. - ✔✔Statistics
It is also a logical grouping of attributes. - ✔✔Variable
Nominal comes from the Latin root 'name' meaning nomen. - ✔✔False
,When the number of elements of the population is fixed and thus making it possible to
enumerate it in totality. - ✔✔c. Finite Population
Knowing the level of measurement helps you decide what statistical analysis is appropriate on
the values that were assigned - ✔✔true
Variable that always goes on the x-axis, or the horizontal axis - ✔✔c. Independent Variable
In ratio scale, variables can be systematically added, subtracted, multiplied and divided. -
✔✔True
It is a characteristic that varies from one individual member of population to another individual.
- ✔✔Variable
It is always possible to transform data from a higher level to a lower level but never the other

temperature of the ocean
It tries to describe the relationship between variables in a sample or population and provides a
summary of data in the form of mean, median and mode. - ✔✔c. Descriptive Statistics
The interval scale gives the ability to quantify and differentiate between options. - ✔✔True
We use statistics when the number of cases that can occur are really small. - ✔✔False
, It is important to study statistics in order to formulate well-advance predictions. - ✔✔True
It is the study of how to collect, organize, analyze, and interpret numerical information from
data. - ✔✔statistics

researcher. - ✔✔False

meaning. - ✔✔False
A set is said to be multimodal if it has _________________________. - ✔✔c. Three or more
modes
Statistical variables do not contain numerical values but rather something
__________________________. - ✔✔Descriptive
These are measurements for which there is no natural numerical scale, but which consist of
attributes, labels, or other non numerical characteristics. - ✔✔c. Qualitative Data
These are often used to communicate research findings and to support hypotheses and give
credibility to research methodology and conclusions. - ✔✔c. Statistical Method and Analyses
It varies according to changes in other variables. - ✔✔a. Dependent Variable
The only permissible aspect related to numbers in a nominal scale is "counting." - ✔✔False
It gives the ability to quantify and differentiate between options. - ✔✔Interval
