    A phone tethered to a laptop. Tethering or phone-as-modem (PAM) is the sharing of a mobile device's Internet connection with other connected computers.Connection of a mobile device with other devices can be done over wireless LAN (), over Bluetooth or by physical connection using a cable, for example through USB.

  4. Data dredging - Wikipedia

    en.wikipedia.org/wiki/Data_dredging

    A hypothesis, biased by data dredging, could then be "people born on August 7 have a much higher chance of switching minors more than twice in college." The data itself taken out of context might be seen as strongly supporting that correlation, since no one with a different birthday had switched minors three times in college.

  5. Mobile phone signal - Wikipedia

    en.wikipedia.org/wiki/Mobile_phone_signal

    One reason for a call to be "dropped" is if the mobile phone subscriber travels outside the coverage area—the cellular network radio tower(s). After a telephone connection between two subscribers has been completed, both the tower and the mobile phone must remain within range of that subscribers network provider or that connection will be ...

  6. Hotspot (geology) - Wikipedia

    en.wikipedia.org/wiki/Hotspot_(geology)

    Geologists have tried to use hotspot volcanic chains to track the movement of the Earth's tectonic plates. This effort has been vexed by the lack of very long chains, by the fact that many are not time-progressive (e.g. the Galápagos) and by the fact that hotspots do not appear to be fixed relative to one another (e.g. Hawaii and Iceland).

  7. Heat map - Wikipedia

    en.wikipedia.org/wiki/Heat_map

    The two heat maps to the right, labeled "Data Analysis Heat Map Example," show different ways in which one may present genomic data over a specific region (Hist1 region) to someone outside the field of biology so they have a better understanding of the general concept a biologist or data scientist are trying to present.

  8. High frequency data - Wikipedia

    en.wikipedia.org/wiki/High_Frequency_Data

    Rather than breaking the sequence of ultra-high frequency data by time intervals, which would essentially cause a loss of data and make the set a lower frequency, methods and models such as the autoregressive conditional duration model can be used to consider varying waiting times between data collection. [5]

  9. Paired data - Wikipedia

    en.wikipedia.org/wiki/Paired_data

    In some cases, the data sets are paired, meaning there is an obvious and meaningful one-to-one correspondence between the data in the first set and the data in the second set, compare Blocking (statistics). For example, paired data can arise from measuring a single set of individuals at different points in time. [1]
