6CC U7 MATH VOCAB

TermDefinition
median the middle score in an order distribution set; half the scores are above it and half are below it
argue Challenge or debate an issue or idea with the purpose of persuading or committing someone else to a particular stance or action.
argument A statement put forth and supported by evidence support.
lower quartile The median of the lower half of a set of data.
distributed equally shared or divided so that each gets the same amount.
generally usually, or in most situations
datum A datum is a singular piece of information, fact, or statistic, or a fixed reference point, surface, or coordinate system used as a basis for measurement, calculations, or mapping. Data is its plural form.
interquartile range (IQR) the difference between the upper quartiles and lower quartile.
measure of variability A single number that presents information about the spread of scores in a distribution. An absolute deviation and interquartile range are measures of variability.
distribution a representation that shows how often values in a data set occur.
box plot a visual display of a data set on a number line that shows the minimum, the lower quartile, the median, the upper quartile, and the maximum. The sides of the box show the lower and upper quartiles and the line inside the box shoe the median. Lines connect to the box to show the minimum and maxiumu values.
consistent Steady; regular
interval The distance between two values in a scale representing data
skewed left When most of the data points of a distribution are clustered near the greater values, with the lower values forming a tale to the left
skewed right when most of the data points of a distribution are clustered near the lesser values, with a higher values forming a tail to the right.
upper quartile The median/middle number of the upper half of a set of data. Between the median and the maximum in an ordered set of data.
mean the arithmetic average of a distribution, obtained by adding the scores and then dividing by the number of scores mean absolute deviation (MAD) the sum of the distances of each data point from the mean of the data set divided by the number of data points. It is always positive.
data a set of collected information. Often numerical information such as a list of measurements.
typical being like others of its kind; usual
gap a region of the distribution where there are no values
histogram a display similar to a bar graph. A histogram groups the data into equal sized interval. The height of each bar representsthe number of data points in the group.
outlier A value much greater or much less than the others in a data set
peak In a distribution, the shape formed when many data points are at one value or group of values.
dot plot a data display that shows data as dots above a number line. A dot plot may also be called a line plot.
frequency a numerical count of how many times a data value occurs in a data set.
cluster A number of similar things grouped together
range the difference between the highest and lowest values in an ordered set of data.
statistical question A question that has many different, or variable, answers. A question that can be quantified.
variability in a set of numbers, how spread out or close together values in a data set are.
measure of center Numbers that are used to describe the center of a set of data. These measures include the mean and median.
mean absolute deviation (MAD) the sum of the distances of each data point from the mean of the data set divided by the number of data points. It is always positive.
symmetric data data sets whose values are evenly spread around the center.
support back up with details and evidence
