Answer:

the researcher is measuring the deviation in the results

Explanation:

The deviation of a statistical result shows how far results depart from the center of the measurement. In other words, the results show how the measurements depart from the mean or average value. By taking the measurement values, the upper limit can be established. Next, the lower limit of the results can be measured. Next, the standard deviation can be measured to determine the nearness of furtherness of the values from the control values. Then, a plot of the standard deviation against the results can be plotted.

Where did the symbols for the democratic and republican parties come from?
shusha [124]

Answer:

Jackson, a hero of the War of 1812 who later served in the U.S. House of Representatives and U.S. Senate, was amused by being called a jacka** from his opponents, and included an image of the animal in his campaign posters. He later went on to defeat incumbent John Quincy Adams, and serve as America’s first Democratic president. In the 1870s, influential political cartoonist Thomas Nast helped popularize the donkey as a symbol for the Democratic Party. For the republican party, it was formed in 1854 and six years later Abraham Lincoln became its first member elected to the White House. An image of an elephant was featured as a Republican symbol in at least one political cartoon and a newspaper illustration during the Civil War.

<u> Hypotheses</u>,<u> dependent</u> and <u>independent variables</u> form a set of tools that help us to create theories about natural phenomena.

Dependent Variable are values ​​(phenomena or facts) to be discovered or explained, by virtue of being influenced, determined or affected by the independent variable.
