Operation Display Correction after pressing      : Correction prior to pressing       immediately after a data entry: Delete incorrect 
data with      , then enter the correct data.
Use             to display the data previously entered.
Press        to display data items in ascending (oldest first) order. To 
reverse the display order to descending (latest first), press the        key.
Each item is displayed with X:, Y:, or F: (n is the sequential number 
of the data set).
Display the data item to modify, input the correct value, then press      . 
Using      , you can correct the values of the data set all at once.
• When   or   appears, more data items can be browsed by pressing  
        or       .
• To delete a data set, display an item of the data set to delete, then   
  press           . The data set will be deleted.
• To add a new data set, press       and input the values, then press      .

APPLICATIONS:
Single-variable statistical calculations are used in a broad range of 
fields, including engineering, business, and economics. They are 
most often applied to analysis in atmospheric observations and 
physics experiments, as well as for quality control in factories.

“ANS” KEYS FOR 2-VARIABLE STATISTICS
In addition to the 1-variable statistic keys, the following keys have been added for calcu-
lating 2-variable statistics.
NOTE:
The codes for basic statistical quantities of sample data x and their meanings
are the same as those for single-variable statistical calculations.
Let’ s check the results based on the previous data.Calculates the sum of the product for sample data x and sample data y.
Calculates the sum of the data (sample data y).
Calculates the sum of the data (sample data y) raised to the second power.
Calculates the average value of the data (sample data y).
Calculates the standard deviation for the data (sample data y).
Calculates the standard deviation of a data population (sample data y).
7.175 (Average for data x)
0.973579551 (Standard deviation for data x)
0.91070028  (Standard deviation of the population for data x)
