Types of Data
What type of variable is shoe size?
What is Quantitative discrete?
Which graph is best for small sets of quantitative data?
What is dot plot or stem plot?
What is the formula for calculating mean?
What is (sum of all values)/(number of all values)?
How is IQR calculated?
What is Q3-Q1?
What does the "S" is SOCS stand for?
What is Shape?
Is "favorite movie genre" categorical or quantitative
What is categorical?
Which type of graph shows data split into quartiles?
What is a boxplot?
Which measure of center is resistant to outliers: mean or median?
What is the median?
What spread measure is affected most by outliers?
What is standard deviation?
What is skewed right?
This type of quantitative data consists of countable values, like the number of students in a class or the number of cars in a parking lot.
What is discrete data?
This type of plot splits each data value into a "Stem" (the leading digit) and a "leaf" (the last digit) to display the distribution while preserving the original data values.
What is a stem plot?
What is 8?
What is the range of this data set: [5, 8, 11, 14, 18]?
What is 13?
What is the typical way to describe a center in a skewed distribution?
What is the median?
True or false: "ZIP code" is a quantitative variable
what visual cue indicates skewness in a histogram?
What is a longer tail on one side?
What is it increases?
If the standard deviation is 0, what does that tell you about the data?
What is all values are the same?
What does an outlier do to the mean?
What is it pulls it towards the outlier?
Prove an example of a categorical variable that can be assigned numerical values.
What is something like "jersey number" or "room number"?
Unlike bar graphs, this type of graph displays quantitative data with adjacent bars, where the width of each bar represents class intervals and height shows frequency.
What is a histogram?
Describe a situation where the mean and median would be equal.
What is a symmetric distribution?
What is the measure of spread that tells you, on average, how far each data point is from the mean, and it's especially sensitive to outliers?
What is standard deviation?
Fully describe a distribution using SOCS for the data set: [1, 2, 2, 3, 3, 3, 3, 4, 10]
What is shape: right skewed, Outlier: 10, Center: median is 3, Spread: range is 9 or IQR is 1.
