Statistics/Data Analysis
Histograms/Frequency Table
step 2:Make ranges of numbers to put the data in to
step 3:Make a histogram chart and fill it out.
step 1: Make a frequency table
Box plots and Line plots
Line plots
Step 2:Organize the data in number order
Step 3:Create a Number Line
Step 1:You put your data into a frequency table
Step 4: Put a mark over were the data occurs
Box Plots
Step 3:Find the IQR and Upper Quartile Range
Step 4:Draw whiskers on the remaining numbers(The ones on the end)
Step 2:Put a line over the median
Step 1:Draw out a number line
IQR-Interquartile range
You find it by adding the upper quartile and lower quartile
Central Tendencies
Range
Step 3:Find the difference between the highest and lowest numbers
Example:2,4,8,12,20 So the to find the range you would have to subtract 20-2=18
Step 2:Find the Lowest and Highest Numbers
Step 1: Arrange from least to greatest
The definition for range is the distance between
Median
Step 2:Find the middle number
Step 3:If there are two middle numbers,find the mean of these two numbers
Example:2,8,13,16,19,21,23 the middle is 16
Definition:Is the middle
when you use median: when the data has an extreme values and there are no big gapes in the middle of the data
Step 1:Order from least to greatest
Mean
step 1: Add all the numbers
step 2: divide addens
Definition: Is the average
Examples: add these numbers up 2,279,14 now just add all the numbers up 2+14+9+27= 52 then divide it by the addiens 52/4=13
when you use mean: when the data has an extreme values and there are no big gapes in the middle of the data
when you use mean: when the data has no extreme value
Mode
step 2: find the number that is repeated the most
Definition: is the most popular and mode means most
step 1: Arrange the numbers from least to greatest
Example: 18,19,18,24,21 now put them from least to greatest 18,18,19,21,24 now which number has the most numbers there 18 has the most numbers there
when you use mode: data have many repeated numbers
Example:
Example:
