Manipulating List Data

u To calculate the median of data items of specified frequency[OPTN]-[LIST]-[Med]

This procedure uses two lists: one that contains values and one that indicates the frequency (number of occurrences) of each value. The frequency of the data in Cell 1 of the first list is indicated by the value in Cell 1 of the second list, etc.

• The two lists must contain the same number of data items. If they don’t, an error occurs.

K1(LIST)6(g)4(Med)6(g)6(g)1(List) <list number 1-26 (data)> ,1(List) <list number 1-26 (frequency)>)w

Example

To calculate the median of values in List 1 (36, 16,

58, 46, 56), whose

 

frequency is indicated by List 2 (75, 89, 98, 72, 67)

u To combine lists

[OPTN]-[LIST]-[Aug]

•You can combine two different lists into a single list. The result of a list combination operation is stored in ListAns memory.

K1(LIST)6(g)5(Aug)6(g)6(g)1(List) <list number 1-26> ,1(List) <list number 1-26>)w

Example

To combine the List 1 (–3, –2) and List 2 (1, 9, 10)

AK1(LIST)6(g)5(Aug) 6(g)6(g)1(List)b, 1(List)c)w

u To calculate the sum of data items in a list[OPTN]-[LIST]-[Sum]

K1(LIST)6(g)6(g)1(Sum)6(g)1(List)<list number 1-26>w

Example To calculate the sum of data items in List 1 (36, 16, 58, 46, 56)

AK1(LIST)6(g)6(g)1(Sum)

6(g)1(List)bw
