Hi guys. Please complete numbers 16 - 22 for your homework tonight. 

Quiz Wednesday - Data

Hello, my wonderful mathlings! Please be sure to review the following concepts for Wednesdays's quiz:

I. Graphing
   A. Intervals
        1. Intervals should be even (count if you need to)
        2. Intervals are usually on the y-axis or are the first category in a frequency chart
        3. Think of intervals as "categories"
   B. Labels
       1. Your graphs should always have a title that pertains to the information being represented by
            the graph
       2. Your x-axis and y-axis should both have labels, even if the information on the graph seems
            obvious
   C. Accuracy
        1. Always re-check your data after you've made your graph
       

II. Measures of Central Tendency
    A. Mean: (average) - add ALL the data, and then divide by how many data points you have
    B. Median: FIRST, line up all the data from LEAST to GREATEST; then, find the middle number.
         If there are two middle numbers, find the MEAN of the two middle numbers for your median.
    C. Mode: number that appears the MOST
    D. Range: highest data point minus the lowest data point

III. Drawing conclusions
   A. Real-world connections - be sure to think about the data in a real-world setting and be sure that
        your conclusions are realistic
   B. Comparisons - when asked to compare data, think about how many TIMES greater one statistic
        is than another, rather than how "much" more
   C. We will focus on this part heavily on the quiz. Please use complete sentences and proofread your
        answers

Survey Project

Hello Mathlings!

Here are the things that need to be included in your project, which is due for presentation this Friday, 10/16.

- Two graphs which represent your data (the graphs you choose will be approved by me after you turn in your project outline Monday) - Both graphs need to be large enough to display to the class. You may present these graphs digitally on the Polyvision Board or with Posterboards. Please remember to label your graphs and to keep your intervals even - you will be graded on the accuracy of your graphs.

- The four measures of central tendency for your data (mean, median, mode and range)

- One written paragraph (6-8 sentences) which explains your survey and draws conclusions based on the data you collected

We will be working on these all week. In addition to your graphs, your measures of central tendency and your paragraph/conclusions, you will be given participation points this week for working with your group and for participating in your group's presentation of information. Please make sure each group member has an opportunity to speak when you present on Friday.

I'm really interested in the questions you've come up with! Have fun with this!!!
