SHAPES
A distribution with a single, central peak where data is heavily clustered in the middle and tapers off symmetrically on both ends (resembling a curve).
What is the MAD of the following data set
3,4,5,3,7,4
1.17.
Create a Dot plot with the following data set: 11,12,15,3,12,7,4,13,11,10,14,12,13,151,6,11,11

Define a non-statistical question
A non-statistical question is a question that has one specific answer and does not require collecting data from multiple sources or people.
A table is a table that shows how often each value or category occurs in a set of data.
Frequency Table
A distribution where a vertical line can be drawn right down the middle so that the left and right sides roughly match up or mirror each other.
WHAT IS SYMMETRIC
What is the MAD of the following data set 12,23,24,13,15
4.88
What graph needs a five-number summary
Boxplot
Is the question Statical or non-statistical? Is the data categorical or Numerical: How old is Michael Jordan?
Numerical Non Statistical
describes a data set using five values:
minimum, Q1, median, Q3, and maximum.
A five number summary
Unlike a normal distribution with a single peak, this type of probability distribution features two distinct modes or local maximums.
WHAT IS BIMODAL
What is the MAD :
the average distance between each data point and the mean of a dataset
What graph needs an x-axis and y-axis
ALL GRAPHS
Define Statistical Question
A statistical question expects different answers and requires collecting data
is a graph that displays the five-number summary of a data set. It shows the minimum, Q1, median, Q3, and maximum.
Boxplot
A graph where the left and right sides are approximate mirror images of each other and are symmetric
Bellshaped
What is the final step in finding the MAD
add all the absolute deviations together, then divide by the number of data values.
Create a histogram with the following data set: 11,2,5,3,12,7,4,13,1,10,4,2,3,5,6,1,11
Answer ona white board
What is the average height of students in our class? What type of question is this, and what data type
Non Stat /numerical
is a graph that shows how often numerical data occurs within intervals or ranges. The bars touch because the data is continuous or grouped into numerical intervals.
Histogram
Exhibiting invariance under a non-trivial isometry—such as a reflection across a hyperplane or a rotation about a central point—this type of geometric figure maps onto itself identically.
Find the MAd of the following: 90,20,3,75,82,45,4,33,0,12
