a dotplot is a simple graph you can use to show the distributions of quantitative variables.
What is a dotplot?
100
it is the final digit of a number.
What is a leaf on a stem and leaf plot???
100
when the rounded percents of a given data do not equal to 100 percent.
What is roundoff errors??
100
what is- an summary that consists of the median, the quartiles, and the high and low extremes and provides a quick overall description of a distribution.
What is a five number summary?
100
these are the key questions you ask yourself when you meet a new set of data?
who, what, why, when,where,how,and by whom
200
The three adjectives that describe a distribution.
Shape, Center, and Spread
200
when u double the number of stems in a plot to show a more defined spread of numbers that are not really that far apart.
What is splitting stems
200
removing the last digit or digits before making a stemplot.
What is trimming?
200
A statistic that looks at how far observations are from their mean.
What is standard deviation?
200
A variable that cannot be assigned a numerical value, just a description
What is a categorical variable?
300
A graphical display of a five-number summary
What is a boxplot?
300
the science (and art) of learning from data.
What is statistics?
300
A piece of data that is more than 1.5 times the IQR away from the 1st or 3rd quartile
What is an outlier?
300
This is the measure of central tendancy that is resistant to outliers
What is the median
300
These types of data take on numerical values for which arithmetic operations such as adding and averaging make sense.
What is a quantitative variable?
400
These can be used when comparing quantitative distributions of 2 different categories or populations.
What are back to back stem plots
400
The group of people/things/places/animals that you are trying to gain information about.
What is a population?
400
This shows how the proportion of data aproaches 100% on a graph
What is a relative commulative frequency graph?
400
Changing the original variable x into the new variable xnew given by the equation of the form. (like curving test scores)
What is linear transformation.
400
This type of data analysis uses graphs and numerical summaries to describe the variables in a data set and the relations among them.
What is exploratory data analysis??
500
a graph that graphs time horizontally and the values of the variable vertically.
What is a time plot?
500
This method of data gathering consists of watching a group of individuals to gain information rather than manipulating a variable or variables in an experiment.
What is an observational study.
500
A relative cummulative frequency graph is also called this.
What is an Ogive
500
this is the equation for a linear transformation graph
What is xnew = ax + b
500
Prodeuces answers to specific questions along with a statement of how confident we can be that the answer is correct. (using stats to predict the future)
