Storyboard Text

  • Mr.Tom I don't know how to solve these problems of central tendency mean,median,mode, range
  • 
  • 6 7 3 8 1 4 5 2 9
  • Ok then time to give you another lesson here try finding the mean in this set of numbers
  • 
  • But how do I find the mean?
  • 1 2 3 4 5 6 7 8 9
  • Well, first you want to sort the numbers from least to greatest. After that you want to add it all together. Then you divide it by how many numbers there was in the set of numbers you have.
  • 45 divided by 9=5
  • (1+2)+(3+4)+(5+6)+(7+8)+9=45
  • Ok thats mean but how do you find median?
  • 1 2 3 4 (5) 6 7 8 9
  • You just find the number in the center in the set if numbers you have, but if there is no center number then you just add the two closest numbers to the center then you divided it by two and there you have the median.  
  • Ok what about mode?
  • 1344578(999)
  • Mode is 9 
  • The mode is easy you just find the number that repeats the most.
  • Ok then what about range.
  • (1) 2 3 4 5 6 7 8 (9)      9-1
  • You just subtract the biggest number from the smallest number
