Data
Data that is measured by numbers.
What is quantitative data?
The (BLANK) of the data set (100, 20, 4000, 1, 6) is 825.4.
Mean.
The (BLANK) is the most basic measure of spread, and it's a term from Algebra.
What is range?
The graph made up of separated rectangular depictions of categorical data.
What is a Bar Graph?
If I have three apples and 2 are red and 1 is green, what is the mode of the distribution of colors.
Apples that are red.
Data that is measured by names.
What is categorical data?
The (BLANK) of the dataset (1, 5, 7, 9, 11) is 7.
Median
The (BLANK) is expressed as +/-[x]
I.E. +/-5
Standard Deviation
A round graph that measures categorical data.
What is a Pie Chart?
If I wake up 66% of the time wanting cereal and 34% of the time wanting pancakes, what kind of graph I want to use to measure my food choices?
Pie chart.
Mode.
The (BLANK) is the measure of the middle 50% of data in a data set.
Inter-Quartile Range
A graph that represents the spread of a quantitative data using adjacent rectangles.
What is a Histogram.
Categorical, because it is not numerical.
I have 62 inches of tape; that's a piece of...
Quantitative data.
What measure of center do you use for categorical data?
Mode.
The IQR is a more appropriate method of measure when compared to range when measuring a skewed dataset BECAUSE....
It is not affected by outliers.
A graph in the form of a number line that measures and displays the distribution, spread, and center of quantitative data. Expressed in individual points.
What is a dot plot?
True or False? The IQR is affected by outliers.
False, it only measures the middle 50%.
If I have 45 cars, and they're a mix of red, blue, and green. What kinds of data are those?
The number of cars is quantitative data, while their color is categorical data.
Which of the following measures of center are NOT affected by outliers? Mean, Median, Mode.
Median and Mode.
True or False? The range is always affected by a change in the mode of the dataset.
FALSE, the range is only affected by the maximum and minimum value of a data set.
The mode is almost always unrelated.
Type of graph that provides: minimum, first quartile, median, third quartile, maximum. Expressed as a horizontal rectangle.
What is something that Median, Mode, and Mean all have in common?
They're all my favorite kind of questions.
Also, they're all measures of center.
