Teaching Strategy: Unit 4 vocabulary graphic organizer
•
•
•
•
Copy the vocabulary words found on page 540 on your graphic organizer.
Find and write out the definitions for each word. (back of the book)
Give an example for each word. (found in chapter 7)
This assignment is due at the end of class today. (NO Cutting or Pasting. This
will go in your new folder.)
Summarizing Strategy: Based on the vocabulary terms, what do you expect to
learn in this unit? (write your answers on the back of your graphic organizer.
Concept: Sampling Populations (SP.1) (SP.2)
Lesson EQ:
1.How can data be collected and used to draw inferences about a population?
2. How do you determine if a sample represents valid results?
KNOW:
Random sampling guarantees that each element of the population has an equal opportunity to be
selected in the sample (SP.1)
A random sample must represent population to make valid inferences (SP.1)
Representative samples can be used to make valid inferences about a population. (SP.1)
A random sample increases the likelihood of obtaining a representative sample of a population.
(SP.1)
A random sample can be used to draw inferences about unknown characteristics of a population.
(SP.2)
DO:
Determine if a sample is valid and representative of a population. (SP.1) (DOK 2)
Use real-life situations to show the purpose for using random sampling to make inferences about a
population. (SP.1) (DOK 2)
Make inferences about a population based on a sample. (SP.2)(DOK 3)
Explore the variation in estimates or predictions based on multiple samples of the same data.
(SP.2)(DOK 2)
Collect and use multiple samples of data to answer question(s) about a population. (SP.2) (DOK 2)
Teaching Strategy:
Chapter 7 Lesson 1 and 2 . Read Examples and complete independent practice.
Summarizing Strategy: H.O.T. p.556 #5 How could the wording of a question or the tone of voice of
the interviewer affect a survey? Provide an example.
Concept: Comparing Populations (SP.3)
Lesson EQ:
1. What are measures of center?
2. What are measures of variation?
KNOW:
•The measure of mean is independent of the measure of variability. (SP.3)
•Variability is responsible for the overlap of two data sets (SP.3)
DO:
•Display numerical data in plots on a number line, including dot plots, stem-and-leaf plots,
histograms, and box plots. (SP.3) (DOK 2)
•Use visual representations to compare and contrast numerical data from two populations using
measures of variability and center. (SP.3) (DOK 3)
Teaching Strategy:
Power Point FIND THE MAD
Power Point Measures of Variation
Power Point Making a Box-And-Whisker Plot
Concept: Comparing Populations (SP.4)
Lesson EQ:
3. What measures are used to compare populations?
4. How can graphs and tables be used to compare data?
KNOW:
•A set of data collected to answer a statistical question has a distribution which can be described by
its center, spread, and overall shape. (SP.4)
•A measure of center for a numerical data set summarizes all of its values with a single number,
while a measure of variation describes how its values vary with a single number. (SP.4)
DO:
•Make comparative inferences about two populations using measures of center and variability.
(SP.4) (DOK 3)
