Capturing Data: Modelling and Interpretation

Reallife contexts, curriculum opportunities and cross-curricular dimensions

Publisher: Texas Instruments UK

Author: Linda Tetlow, Ian Galloway, Adrian Oldknow

Topic:  Mathematics  STEM

Tags  Data

The data handling features of TI-Nspire and the emphasis in the secondary curriculum on reallife contexts, curriculum opportunities and cross-curricular dimensions all combine to give a strong rationale for introducing activities using TI-Nspire which use real data and link STEM subjects.

There is a wealth of data available on the Internet in a variety of forms. TI-Nspire can make use of this data as it has the facility to copy and paste information from tables and spreadsheets into a Lists & Spreadsheet page. Data can also be captured using a variety of data logging probes linked to TI-Nspire handheld, such as temperature probes or motion sensors. It is then possible to manipulate, display and analyse this data in a variety of ways using facilities from ‘Data and Statistics’. It is also possible to further analyse or attempt to model the data by inserting movable lines, plotting functions or fitting a variety of functions using different forms of regression.
