Data may be classified by one of the four levels of measurement. What is the name of the lowest level?

coldgirl [10]

Answer:

Nominal

Step-by-step explanation:

There are four levels of measurement of data listed below in increasing order:

Nominal

Ordinal

Interval

Ratio

The nominal level of measurement is the lowest level that deals with names, categories and labels. It is a qualitative expression of data e.g Colors of eyes, yes or no responses to a survey, and favorite breakfast cereal all deal with the nominal level of measurement.

Data at this level can't be ordered in a meaningful way, and it makes no sense to calculate things such as means and standard deviations.

a picture 10 1/4 feet long is to be centered on a wall that is 14 1/2 feet long. How much more space is there from the edge of t

Zarrin [17]

Answer:

Length from the edge will be $=2{\frac{1}{8}}$ feet

Step-by-step explanation:

To find length we have to conver mixed fraction to improper fraction

The length of the wall $= \frac{29}{2}$

Length of picture $=\frac{41}{4}$

First we find the total length of wall remain after picture was hung to the wall.

Length of wall remain vacant $=\frac{29}{2}-\frac{41}{4}$

Taking LCM and solving we get

$=\frac{58-41}{4} =\frac{17}{4}$

Total length of wall remain vacant $=\frac{17}{4}$

As the picture to be centered in wall, therefore space feom one edge of wall will be half that of length remain vacant as the same length to be left vacant feom both sides.

Space from one edge $=\frac{17}{4} \times \frac{1}{2}$
