The weight Lucy lost with respect to number of weeks was recorded for six weeks. The correlation coefficient was calculated to b
Aleonysh [2.5K]

Answer: There is a weak, positive correlation between the weight Lucy lost and the number of weeks.

Explanation:

The correlation coefficient is used to measure the relationship between two variables in terms of how they move in relation to one another.

If two variables are said to have a positive correlation, it means that they increase at the same time and decrease at the same time for example, there is a positive correlation between the amount of food a family buys and how much money they have because the more money they have, the more food they buy.

Negative correlations are the reverse for instance Ice cream sales and cold temperatures. The colder it is, the less people buy ice cream.

The Correlation coefficient ranges from -1 to +1 with +1 (-1) meaning that the variables are perfectly positively(negatively) correlated. The closer the value is to 0, the weaker the correlation.

Generally, for a correlation coefficient between the numbers 0 and +0.3, there is a weak positive correlation.

With a correlation coefficient of 0.0502, there is therefore a weak, positive correlation between the weight Lucy lost and the number of weeks.

algol13

Explanation:

The Abbasid caliphs established the city of Baghdad in 762 CE. It became a center of learning and the hub of what is known as the Golden Age of Islam.

The Islamic Golden Age refers to a period in the history of Islam, traditionally dated from the 8th century to the 13th century, during which much of the historically Islamic world was ruled by various caliphates and science, economic development, and cultural works flourished. This period is traditionally understood to have begun during the reign of the Abbasid caliph Harun al-Rashid (786–809) with the inauguration of the House of Wisdom in Baghdad, where scholars from various parts of the world with different cultural backgrounds were mandated to gather and translate all of the world’s classical knowledge into the Arabic language.
