What |are |statistics? |- |✔✔Statistics |encompass |the |mathematical |field |that |allows |us |to |organize, |
summarize, |describe, |and |interpret |different |forms |of |information.
Name |3 |reasons |why |statistics |are |important |- |✔✔1. |Statistics |allow |data |to |be |described |and |
communicated |succinctly |and |concisely. |
2. |Statistics |allow |inferences |to |be |drawn |about |data, |particularly |when |it |is |not |feasible |to |collect |
information |from |all |members |of |a |certain |group.
3. |Statistics |equip |us |with |the |necessary |tools |needed |to |critically |evaluate |information.
Qualitative |variables |- |✔✔Variables |measured |in |non-numerical |terms, |using |categories |or |labels
Quantitative |variables |- |✔✔Variables |measured |in |numerical |terms
Discrete |variables |- |✔✔Those |that |hold |discrete |values, |such |that |they |can |be |organized |into |
separate |categories |or |counted |using |whole |numbers
Continuous |variables |- |✔✔Variables |that |can |theoretically |be |broken |down |into |infinitely |smaller, |
fractional |components
Name |at |least |3 |examples |of |qualitative |variables |- |✔✔One's |religion, |ethnicity, |eye |color, |and |career
Name |at |least |3 |examples |of |quantitative |variables |- |✔✔Weight, |height, |heart |rate, |and |test |scores
Describe |the |important |variables |involved |in |an |experimental |study |- |✔✔The |variable |that |is |

What |are |statistics? |- |✔✔Statistics |encompass |the |mathematical |field |that |allows |us |to |organize, | summarize, |describe, |and |interpret |different |forms |of |information. Name | 3 |reasons |why |statistics |are |important |- |✔✔1. |Statistics |allow |data |to |be |described |and | communicated |succinctly |and |concisely. |

  1. |Statistics |allow |inferences |to |be |drawn |about |data, |particularly |when |it |is |not |feasible |to |collect | information |from |all |members |of |a |certain |group.
  2. |Statistics |equip |us |with |the |necessary |tools |needed |to |critically |evaluate |information. Qualitative |variables |- |✔✔Variables |measured |in |non-numerical |terms, |using |categories |or |labels Quantitative |variables |- |✔✔Variables |measured |in |numerical |terms Discrete |variables |- |✔✔Those |that |hold |discrete |values, |such |that |they |can |be |organized |into | separate |categories |or |counted |using |whole |numbers Continuous |variables |- |✔✔Variables |that |can |theoretically |be |broken |down |into |infinitely |smaller, | fractional |components Name |at |least | 3 |examples |of |qualitative |variables |- |✔✔One's |religion, |ethnicity, |eye |color, |and |career Name |at |least | 3 |examples |of |quantitative |variables |- |✔✔Weight, |height, |heart |rate, |and |test |scores Describe |the |important |variables |involved |in |an |experimental |study |- |✔✔The |variable |that |is | manipulated |in |an |experiment |is |known |as |the |independent |variable, |and |the |variable |that |is | measured |for |any |observable |effect |is |known |as |the |dependent |variable. |A |control |variable |is |a |

variable |that |remains |unchanged |throughout |the |experiment. |Extraneous, |or |confounding, |variables | include |any |variables |that |could |unintentionally |affect |the |dependent |variable. Suppose |you |want |to |study |the |effects |of |a |genetically |modified |diet |on |the |weight |of |dogs. Give |at |least | 3 |examples |of |extraneous |variables. Explain |why |the |variables |are |extraneous. Why |is |important |to |identify |extraneous |variables |in |an |experimental |study? |- |✔✔1. |Activity |level: | Dogs |given |more |space |and |opportunity |for |exercise |may |burn |more |calories, |thus |affecting |the | weight.

  1. |Genetics: |Different |breeds |of |dogs |may |be |prone |to |gain |weight |at |different |weights.
  2. |Environment: |Whether |a |dog |is |kept |inside |or |outside |may |impact |weight. Extraneous |variables |may |have |an |effect |on |the |dependent |variable |and |could |skew |the |results |of |the |experiment. |They |may |also |lead |the |researcher |to |draw |incorrect |conclusions. Why |is |it |important |that |extraneous |variables |be |taken |into |account |in |an |experimental |study? |- | ✔✔Extraneous |variables |may |have |an |effect |on |the |dependent |variable |and |could |skew |the |results |of |an |experiment. What |is |an |ordinal |scale |of |measure |- |✔✔Used |to |describe |qualitative |variables, |provide |both | categorical |information |as |well |as |rank |by |size |or |measure What |is |a |nominal |scale |of |measure |- |✔✔Used |to |describe |qualitative |variables, |provides |only | categorical |information What |is |a |ratio |scale |of |measure |- |✔✔Used |to |describe |quantitative |variables |wherein |there |exists |an |absolute |zero |(e.g. |height |and |weight) What |is |an |interval |scale |of |measure |- |✔✔Used |to |describe |quantitative |variables |wherein |an | absolute |or |meaningful |zero |does |not |exist |(e.g. |temperature)
