Happy Monday! Please place your vocab sheets in the front bin.
Please turn in anything that was due Friday on my desk. This week we begin stats so get that GDC! Please have your binder and writing utensil out to begin class when the bell rings.

Bellringer Mental Math- I am going to give you numbers and operations to compute in your head. When I say “go ahead”, write down the number you came up with.

Today’s Objectives SWBAT :
1. Identify data as categorical, quantitative discrete or quantitative continuous data. 2. Organize data into frequency tally charts, dot plots and column graphs, given a set of quantitative discrete data. 3. Use organized data to find a frequency polygon and relative frequency. 4. Describe quantitative discrete using symmetry and outliers.
4
Describing Data Categorical: describes a quality or characteristic. (color of eyes, gender, genre, etc) Quantitative: has a numerical value (number of people, score, length, etc) Quantitative Discrete: Has exact number values (number of something, etc) Quantitative Continuous: Numerical values within a certain continuous range (weight, height, etc)

Presenting Categorical Data
Tally and Frequency Table Vertical column graph Horizontal bar chart Pie chart Segment bar chart
8
Presenting Discrete Numerical Data
Tally and Frequency Table Dot Plot Stemplot
10
Tally and Frequency Table
Easiest way to first organize data.
11
Column Graph Now, using this data, create a column (bar) graph.
12
Frequency Polygon Using your column graph, connect the midpoints of each column.
13
Dot Plot Use the data from the frequency –tally chart and create a dot plot. Each dot represents a recorded value. The height indicates the frequency.

Describing Data Skewed Data- shift in data Outliers- appear separated
from the other data.
