What is the mode used as a measure of central tendency?
It is the data value that is observed most often.It is the data value that is observed most often.It is the data value that is observed most often.It is the data value that is observed most often.
What are the upper and lower quartiles of the data set?
The upper quartile is the value such that a quarter of the data are greater than that value. Similarly, the lower quartile is the value such that a quarter of the data are lower than that value.
Why is the mean an estimated value and not the true value?
The mean is an estimated value because it is calculated based on a sample of data rather than the entire population. Sampling variability can cause the mean of a sample to differ from the true population mean. Additionally, the mean is sensitive to outliers and skewed data, which can further affect its accuracy as an estimate of the true population value.
Single value or piece of data from the data series?
Data Point
What is the minimum data value in a data set?
The minimum data value in a data set is simply the lowest value of the set (easily found by arranging the set from lowest-highest values in an excel sheet or by hand).
In math class using given data to estimate a value beyond the known values is?
It is called extrapolation.
To use given data to estimate a value beyond known values?
It is called EXTRAPOLATION and should only be used with great care.
What is to use a given data to estimate a value between known values?
interpolation
What data is organized and presented in a manner that has additional value beyond the value of the data itself?
Information is the form of data that is organized and presented in a manner that has additional value beyond the value of the data itself.
What is it called When you estimate using a graph beyond measured data in science?
models
When you extend a line beyond your data points to predict the value outside your data points you?
extrapolate
What is the mode and median?
Both median and mode are the statistics formulas, Median is called mid value of the given data and mode is the value which occure repetedly in the given data.
What is it to use given data to estimate a value beyond the known values?
It means to decide what the next thing would be based on the things you already know. For example, if you had a linear equation (a graph where the line is completely straight) and you knew three points, you would be able to use the three points (the known values) to figure out what the fourth or fifth points (the value you are estimating) would be based on the space between each point (the given data).It is called extrapolation (or forecasting) and is usually subject to quite large errors.
Define range in mathematics?
The range is the maximum value in a given data minus its minimum value
A data value that is much higher or lower than any other data values in a set?
the data value that is much higher or lower than the other data given is called an outlier
What are the three components to data definition?
Type, name and initial value. If a value is not given and the type supports default construction, a default value is assigned.
What does Interpolating data means to?
It means to estimate a function value, based on nearby values.For example: let's assume you know that root(20) = 4.4721 (i.e., the square root of 20), and root(21) = 4.5826. If you want the root of 20.5, you can estimate this to be the average of these two, or about 4.5274. This assumes that in the graph of square roots, drawing a straight line between the two extremes is a good approximation. In this example, the exact value (rounded to four decimals) is 4.5277. Note: The term "interpolation" is used if you estimate a value BETWEEN two given values; if you use similar methods to estimate a value OUTSIDE the two given values, the term "extrapolation" is used instead.
