“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)
9.875 (Average for data y)
3.440826313 (Standard deviation for data y)
3.218598297 (Standard deviation of the population for data y)
8 (Total count of data)
57.4 (Sum of data x)
418.48 (Sum of data x raised to the second power)
544.1 (Sum of the product of data x and data y)
