Textbook Problem

Calculate *SP* (the sum of products of deviations) for the following scores. *Note:* Both means are decimal values, so the computational formula works well.

X |
Y |

0 | 2 |

0 | 1 |

1 | 0 |

2 | 1 |

1 | 2 |

0 | 3 |

To determine

**To calculate:** The sum of products of deviations *(SP).*

Explanation

**Given info:**

The given scores are:

X |
Y |

0 | 2 |

0 | 1 |

1 | 0 |

2 | 1 |

1 | 2 |

0 | 3 |

**Calculation:**

The sum of products of deviations is calculated as:

Where *X*, *Y* is for scores and *n* is for number of scores. The below table showing the calculations needed for calculating the sum of products of deviations *(SP)*:
