the trend on the graph, skewed right, left, or symmetrical
shape
Collecting and analyzing data
Statistics
something that cannot be averaged, so usually not numerical, and is usually divided into categories
categorical (qualitative)
In categorical or quantitative data sets, good to see the frequency of results
Similar to a frequency table, but shows two influencing categories instead of one, like how many are male and play soccer
two way table
the mean or median of the graph
center
the process of inspecting data while trying to make conclusions from it
data analysis
data that is numerical where an average can be taken, essentially the opposite of categorical
quantitative
when wanting to show the percent frequency
relative frequency table
An x axis that is numbered according to the range of data, with dots or marks above the data’s corresponding value
dot plot
the variability across the graph, sometimes the range
spread (variability)
anything/anyone being used to collect data, can be people, cars, etc
individuals
the distribution of some variables that ignore the distribution of the whole data set
marginal distribution
Displays an x and y axis that the values are inserted into to see where the bars rise to
bar graph
A y axis that is labeled based on the first number of any multiple digit numbers, with the corresponding single digit values stemming out from this
stem plot
any variable that stands alone or is unusual in the data set
outlier
Any characteristic, number, etc that can be measured or counted
variables
the distribution of values pertaining to one variable after specifying the values of the other variables
A circle divided into slices of pie based on which pieces of data are most prominent
pie chart
Similar to a bar graph, but displays intervals of data rather than specific numbers
histogram
gives you a rough idea of what the graph looks like
5 number summary
the direction the graph is leaning towards, for ex, a graph with more on the left and less on the right is skewed right
skewed
the measurement of the amount of variability or dispersion in a set of values
Standard deviation (SD)
Similar to a bar graph, but the bars are divided into the frequencies of two or more variables
segmented bar graph
Good to find quartiles, medians, and outliers easily and visualize the spread of the data
box and whisker plot
