What values must be considered when creating scale for each axis?
The range of values in the data to be plotted.
What is a data display in which the fequencies of different values are represented by small round points?
It could be a frequency chart.
What is the sum of the data divided by the number of data values?
It is the mean average of number of collected data values.
What kind of data set that cannot be represented by a tree but can be represented by a more general graph?
yep
If the variance of the data values in a sample is 169 what is the standard deviation of the data values?
For a sample, the SD is 13.53, approx.
What values must be considered when creating scale for each axis?
The range of values in the data to be plotted.
What computer measures data on a scale with many values?
Analog computer
What is an appropriate scale and interval for a data set in a table?
The answer will depend on the data values: there is no rule that fits all situations.
What is a continuous data?
a piece of data that keeps changing like someones height or shoe size. * * * * * NO. Continuous data are those that can take all possible values within some given range (which may be infinite), or set of ranges. Discrete data, on the other hand, can only take values from a set (again, possibly infinite). These are usually integer values, but not necessarily so. Height is a continuous variable, but shoe size is a discrete variable.
Is it possible to calculate the coefficient of variation using relative values instead of absolute values?
The coefficient of variation should be computed only for data measured on a ratio scale, as the coefficient of variation may not have any meaning for data on an interval scale. Using relative values instead of absolute values can cause the formula to give an incorrect answer.
What percentage of the data values represented on a box plot falls between the lower quartile and the upper quartile?
gggggww
What does analogue data mean?
Analogue data is data in a continuous stream that has an infinite range of values that change gradually. One example of analogue data is the sound of a person talking. We are capable of handling analogue data, yet computers require analogue data to be converted into digital data for processing.
What is Data that has infinitely many possible values that correspond to a scale that covers a range of values without gaps interruptions or jumps?
It can be data over any single interval in the set of real numbers.
What is a data display in which the fequencies of different values are represented by small round points?
It could be a frequency chart.
What is ordinal statistics?
Ordinal statistics or data is classified as ordinal if the values can be rated on a scale or put i order. Ordinal data can be counted but never measured.
Why need to turn un-normalization data into 1NF?
Un-normalization of data will return the actual values of outcome, which is real value. Because we scale the data in normalization process.
What is the definition of datatypes in programming?
A data type defines how data is represented. All data is obviously represented by a sequence of binary values, however, the data type determines how that value is to be interpreted by the language compiler. Object oriented programming languages use classes to define data types, which not only defines the representation of data but also which operations are valid for the type.
