Notes
IV and DV
IV: is the thing that gets manipulated or changed
DV: The thing that gets affected because of the manipulation ( The outcome.)
For Example: There are 2 Toyotas. One has a new brake, but the other has an old brake.
Then the cars are raced and they calculate the distance both cars whent without stopping.
IV:What got manipulated? The brake, 1 car got a new one.
DV: What was affected? The distance before stopping.
For Example: There are two bananas. One is peeled and the other is not. Which one is the
one that will brown first?
IV: What got manipulated? The banana peel. One was peeled but the other was not.
DV: What was affected? THe outcome of which one browned faster.
Sig Figs (Significant Figures)
Leading zeros: are not significant. EX: O.OO32 The leading zeros are the two zeros
between the decimal . and the 3. Those are not significant. There are only 2 significant
figures in the numbers. The 3 and the 2.
Trailing zeros: are significant if they have a decimal For EX: 3,000 The trailing zeros are
the zeros behind the 3. These ones are not significant because there isn’t a decimal, so
this number has only 1 sig fig. In the number 3,000. the 3 zeros are significant because
there is a decimal behind the 3 zeros, so this number has 4 sig figs.
Non zero digits: are always significant. EX: 1, 2, 3, 4, 5, 6, 7, 8, 9. This is easy to
remember, I’ts only the REAL numbers.
Between zeros: any zero between two numbers is significant. EX: 0.00908 The highlighted
zero is sandwiched between two REAL numbers so therefore it is significant. So this
number has 3 sig figs. In the number 0.009 008 In this number there are four sig figs; the
twos are significant because they are sandwiched between the numbers 8 and 9. The 8 and
9 are REAL numbers so they are significant, the two zeros are sandwiched between two
