Q4, W4: April 19th – 23rd Regular Math

Focus 5: Statistics Assignment List  Focus 5 Statistics IXLs List

Teacher Felicia Taylor Regular Math 7th 30 Focus 5: Statistics
Standard(s) Taught

Use measures of center and measures of variability for numerical data from random samples to draw informal comparative inferences about two populations.

Learning Targets and Learning Criteria

Students are successful when they can…

• compare two data sets for variability by comparing graphs and explain the significance of any visual overlap.
• explain orally and/or in writing why it makes sense that the greater the variability, the more visible the overlap on graphs presenting two numerical data sets.
• model and compare two-real world data sets by measuring the difference between centers and expressing it as a multiple of a measure of variability.
• compare and contrast two populations by using the means and/or medians of data collected from random samples using appropriate vocabulary.
• compare and contrast two populations by using the mean absolute deviations and/ or interquartile ranges of data from random samples.
• read and interpret data from statistical representations (box-and-whisker plot, line/dot plot).
Classroom Activities

Monday (2nd and 4th Period Students) / Tuesday (Innovative and 6th & 8th Period Students)

1. i-Ready Growth Check
2. Complete teacher assigned lessons (standard MAFS.7.SP.2.3) – due Friday 04/23/21
1. Using Mean and Mean Absolute Deviation to Compare Data
2. Using Measures of Center and Variability to Compare Data

Wednesday (All Students)

1. Instruction –  Measures of Center and Variation
1. Definitions
1. mean – the average number in a data set.  Find the sum of all values in the set of data.  Divide by the total number of values.
2. median – the middle number in a set of data when all numbers are arranged from lowest to highest.
3. mode – the value that occurs most often in a set of data.
4. range – the difference between the smallest and largest values in a set of data.  Subtract the smallest value from the largest.
5. upper quartile – the median of the upper half of a set of data.
6. lower quartile – the median of the lower half of a set of data.
7. interquartile range – the range of the middle half of a set of data.
8. outlier – a number in a set of data that is either much greater or smaller than the median.
2. Assignments – due Friday 04/23/21
