The nominal level is information that have the right to be put in a category. The Ordinallevel is information that can be put in a category and also put in order. The interval level is data that have the right to be put in order and also uncover distinctions between values. The ratio level is data that have the right to be put in​ order, find distinctions between​ worths, and also uncover ratios of worths.Answer: The nominal level is information that deserve to be put in a category. The Ordinallevel is information that have the right to be put in a category and also put in order.

You are watching: Select all the levels of measurement for which data can be qualitative.


The statement is false. A true statement is​ "For data at the interval​ level, you have the right to calculate systematic differences in between data​ entries."
More types of calculations can be performed via data at the nominal level than through information at the interval level.
False. More types of calculations can be performed through data at the interval level than with information at the nominal level.
The level of measurement of information determines which statistical calculations are meaningful. The four levels of​ measurement, in order from lowest to​ greatest, are​ nominal, ordinal, interval and also ratio. The table listed below summarizes what calculations are coherent for each level.Level of MeasurementPlaced information in categoriesArrange information in orderSubtract data valuesDetermine if one data value is a multiple of anotherNominalYesNoNoNoOrdinalYesYesNoNoIntervalYesYesYesNoRatioYesYesYesYesOK
The four levels of​ measurement, in order from lowest to​ highest possible, are​ nominal, ordinal,​ interval, and ratio.Documents at the nominal level of measurement are qualitative just. Documents at this level are categorized using​ names, labels, or attributes. No mathematical computations deserve to be made at this level.Data at the ordinal level of measurement are qualitative or quantitative. Documents at this level can be arranged in​ order, or​ ranked, but distinctions in between information entries are not coherent.File at the interval level of measurement are quantitative just. Data at this level deserve to be ordered and differences between data entries are​ meaningful, however a zero entry is not an innate zero.Data at the proportion level of measurement are quantitative just. Data at this level are comparable to information at the interval​ level, via the added residential or commercial property that a zero enattempt is an innate zero.
Qualitative data consist of​ characteristics, labels, or nonnumerical entries. Quantitative information consist of numerical measurements or counts.OK
What is an inherent​ zero? Describe three examples of information sets that have actually natural zeros and three that do not.
An natural zero is a zero that means none.Maximum wind speed during a hurricaneAverage monthly precipitation in inchesMedian age of college students in years
In an​ experiment, a therapy is applied to component of a populace and also responses are observed. The researcher in an experiment deliberately impacts the responses.In an observational​ study, a researcher procedures attributes of interest of a part of a populace however does not readjust existing conditions. The researcher in an observational research does not influence the responses.Next off Question
With a random​ sample, each individual has actually the same chance of being selected.With a basic random​ sample, all samples of the very same size have the very same chance of being schosen.Answer With a random​ sample, each individual has the very same opportunity of being selected. With a basic random​ sample, all samples of the same size have actually the exact same opportunity of being schosen.
Replication is repetition of an experiment under the very same or similar problems. Replication is necessary bereason it enhances the​ validity, or the accuracy and​ relicapability, of the results.Next Question
A placebo is a fake therapy offered in experiments. To minimize the possibility of the subjects reacting favorably to a​ placebo, the subjects will typically be blinded regarding whether they are receiving a actual treatment or the placebo.Next off Question
Blinding is a technique in which the topics of an experiment perform not understand whether they are receiving a treatment or the placebo. In a​ double-blind experiment, neither the experimenter nor the topics understand if the subjects are receiving a therapy or the placebo. The experimenter is indeveloped after all the information have actually been built up.
A organized sample selects members at consistent intervals from a random starting suggest.OKFor stratified​ samples, members of the populace are split right into 2 or more​ subsets, called strata. A sample is then randomly schosen from each of the strata. This ensures that members of each group within the population will be sampled.Next off Question
A organized sample is a sample in which each member of the population is assigned a number. The members of the population are ordered in some​ method, a starting number is randomly​ schosen, and then sample members are schosen at continual intervals from the founding number.Next Question
What is an benefit of utilizing a​ stem-and-leaf plot instead of a​ histogram? What is a​ disadvantage?
In a​ stem-and-leaf plot, each number is separated into a​ stem, such as the​ entry"s leftmost​ digits, and also a​ leaf, such as the rightmany digit. Tbelow must be as many type of leaves as there are entries in the original data set and the leaves have to be single digits. A​ stem-and-leaf plot is similar to a histogram yet has actually the benefit that the graph still consists of the original information. Another benefit of a​ stem-and-leaf plot is that it offers a straightforward means to kind information.OKAdvantage: Stem-and-leaf plots contain original data values wright here histograms perform not. Disadvantage: Histograms quickly organize information of all sizes where​ stem-and-leaf plots execute not.
In a dot​ plot, each information entry is​ plotted, making use of a​ allude, over a horizontal axis. A​ stem-and-leaf plot, each number is separated into a stem and a leaf.Both plots have the right to be provided to identify certain data entries.Your answer is correct.B.Both plots show just how information are spread.Your answer is correct.D.Both plots can be provided to determine unusual information values.
