Are Bar Graphs used to display comparisions between nominal data?
Yes they are.
The pie graph is used for what kind of data?
Any kind of data - nominal, ordinal or interval - provided you can group the data into a few categories. Ideally not more than seven, though in exceptional cases, up to ten may be used.
Which is an appropriate display to show the measures of variation for a data set?
There are a number of appropriate displays to show the measures of variation for a data set. Different graphs can be used for this purpose which may include histograms, stemplots, dotplots and boxplots among others.
Difference between chi square and Anova?
ANOVA is a statistical test of whether the means of several groups are all equal. The chi-square test of association is used to test the null hypothesis that there is no association between two nominal scale variables. It does not require a distinction between independent and dependent variables.
What is the measure of central tendency for nominal and ordinal data?
The mode can be used with both kinds of data. The median may be used with ordinal data but great care is required if the median falls between two classes of observations.The mode can be used with both kinds of data.

Nominal data is characterized as data that is used to define a group of category. Some examples include color of eyes, and color of hair.

What is a nominal number?
Nominal numbers are numbers used for identification only. They do not indicate quantity, rank, or any other measurement. The properties of nominal numbers are the minimum required to refer to an entity as a number. The term "nominal number" is quite recent, and appears to have originated as a usage in school textbooks derived from the statistical term "nominal data", defined as data indicating "...merely statements of qualitative category of membership." Mathematicians would typically describe this concept simply as a mapping between objects, or sets of objects, to the ordinal numbers.
What is Physical safeguards?

Which one of the following routines measures the amount of memory used by a data structure?

What is used to describe a set of data where the measures cluster or concentrate at a point?
The answer depends on the type of distribution for the data. It could be the modal class.
What instrument is used to collect humidity data?
A hygrometer is used to collect humidity data. It measures the amount of water vapor in the air to determine the humidity level.
IS A PHONE NUMBER A NOMINAL IN STATISTICS?
Yes, a phone number is considered a nominal variable in statistics. Nominal variables are categorical data that represent distinct categories without a meaningful order or ranking. Since phone numbers are used to identify individuals or entities and do not have inherent numerical value or order, they fit this classification.
