Question

Here is a bivariate data set.

x | y

58.1 | 55.3 |

43.3 | 33.7 |

74.5 | 36.9 |

56.2 | 27.7 |

54.4 | 1 |

58.2 | 45.6 |

56.2 | -10.2 |

50.9 | 84.1 |

47.7 | 39.3 |

Find the correlation coefficient and report it accurate to three decimal places. r =

Answer #1

Solution:- given that

x : 58.1,43.3,74.5,56.2,54.4,58.2,56.2,50.9,47.7

y : 55.3,33.7,36.9,27.7,1,45.6,-10.2,84.1,39.3

The correlation coefficient r = -0.065 (rounded)
