Both calculators need four (4) AAA batteries for power. The display (160 x 100 pixels) is bigger and allows the user to see the plots much better. Its CPU processes much more data at a faster speed.
Ti 84 plus ce vs ti nspire cx upgrade#
The TI-89 is major upgrade over the TI-83 Plus. The TI-84 Plus CE only has a mini-USB port (in contrast, the TI-83 only has an I/O port). This feature allows the user to see a graphing request in better detail. The color display on this TI-84 is much bigger (320 x 240 pixels). Its CPU is three times faster than the TI-83 Plus CPU. The TI-84 uses a rechargeable battery (designed to last around two weeks on single charge) instead of AAA batteries. The TI-84 Plus CE has slimmer body than the TI-83 Plus. Both calculators have an I/O port but the TI-84 Plus also includes a mini-USB port. The devices also are powered by four (4) AAA batteries. The processor on the TI-84 has a faster clock (operates at 15 MHz instead of 6 MHz (TI-83 Plus)), therefore it should process requests a little faster. Both calculators use the same type of central processing unit (CPU) (Zilog Z80), and the displays are the same (96 x 64 pixels). In fact, the only difference is that the TI-84 has a mini-USB port while the TI-83 does not.

You can download a tns demonstration document here: The averageif can easily be defined in the equation from the last section. The TI-Nspire has two built in functions countif and sumif. TI-Nspire CX II: The functions countif and sumif Returns the arithmetic average of L that are greater than or equal to 4.ĪVERAGEIF(L, criteria) = SUMIF(L, criteria) ÷ COUNTIF(L, criteria) Sums all the element's of L that are greater than or equal to 4. SUMIF(L, criteria): returns the sum of all the elements that fit a criteriaĪVERAGEIF(L, criteria): returns the arithmetic average of all the elements that fit a criteriaĬounts all the elements of L that are greater than or equal to 4. Three popular spreadsheet functions are operating on elements of a list contingent of a criteria.ĬOUNTIF(L, criteria): returns a count of all the elements that fit a criteria
