After watching the Heisman awards show the other night, I started thinking about my classes recent attempts at verifying the validity of surveys. The way that I see it, the Okie QB should not be holding the hardware right now if Superman got the most first place votes, and I am not a Gator fan at all, as the picture should prove! -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
At any rate, our class has determined that a valid survey should represent exactly 100% of the group that was surveyed. That seems to make sense, as, if there were five people asked to respond, you should have five responses, not 4 or 12 ;-}-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
However, we determined that this all becomes a little trickier if we blend the way that the results are recorded into a mush of fractions, percents, and decimals. ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Now the challenge ensues. See if you can figure out if the following survey could be valid. ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
All of the teachers at CCE were asked to provide one response each to the following question; How could CCE best improve the CCE experience for our students?------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
0.22 of the teachers replied that Mr. P. and Mr. D. should not be allowed to wear Steelers football clothing.--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1/5 of the teachers replied that Mrs. H. should hold no more than 12 tech meetings a week.-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
30% of the teachers stated that Mrs. Phillips should lobby for overtime pay for time spent scoring diagnostic tests. --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
0.125 of the teachers said that Coach Hall should have a Character Ed. class for the teachers.------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1/8 of the teachers said that Mrs. Phillips, the math teacher, should write all lesson plans for all math teachers.------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
3% of the teachers said that lunch should be catered by P.F. Changs.------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
1/4 of the teachers said that there should be no more surveys ever.-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Please look for combinations that "simply must go together". Are there any amounts that are equivalent? Would it help to know that 0.125 could be read as one hundred twenty-five thousandths or 12 and one half hundredths or 12 1/2% ? ----------------------------------------------------------------------------------------------------------------------------------------
Well, is it mathematically valid? -----------------------------------------------------------------------------------------------------------------------------------------------------------------
Peace and Happy Holidays!

Mr. Ruark,
If not for those teachers who don't like surveys, I think it would be OK. I, however, must object to the no Steeler football clothing comments. Please send me a list of those who responded that way.
Mr. P.
Mr. Ruark,
I can't tell you a math answer. But I will tell you I like the idea of Mrs. Hall doing Character Ed for the teachers! :)
Mrs. H
