    • What does the SD tell you?

      How much the values in a single sample vary
    • What is SD a measure of?
      The spread of values about the mean
    • What does a large SD mean?
      the values in the sample vary a lot
    • what does a small sd mean?
      most of the sample data is around the mean, so varies little
    • differing SD from google
    • What can standard deviations be plotted on?
      A graph or chart of mean values using ERROR BARS
    • What do error bars do?

      extend one SD above and one SD below the mean (so the total length of error bar is twice the SD)
    • a longer error bar =?
      Larger SD and the more spread out sample data is from the mean
    • Where is the mean?
      IN the middle of the error bar
