Why are mean median mode and range considered measures of central tendency?

Range is NOT a measure of central tendency. In a number of distribution - though by no means all - the mean, median and mode are near the middle of the distribution. That is more likely to be the case with a large number of observations (or experiments).


How does the median affect the graph of a normal distribution?

A normal distribution is symmetrical; the mean, median and mode are all the same, on the line of symmetry (middle) of the graph.


What is a skewed right?

A distribution or set of observations is said to be skewed right or positively skewed if it has a longer "tail" of numbers on the right. The mass of the distribution is more towards the left of the figure rather than the middle.


Why is it a useful value to report standard deviation?

The standard deviation of a distribution is the average spread from the mean (average). If I told you I had a distribution of data with average 10000 and standard deviation 10, you'd know that most of the data is close to the middle. If I told you I had a distrubtion of data with average 10000 and standard deviation 3000, you'd know that the data in this distribution is much more spread out. dhaussling@gmail.com


Describe the properties of a normal distribution?

A normal distribution is symmetric and when looked at on a graph, the graph looks like a bell shaped curve. Approximately 95 percent of its values should lie within two standard deviations of the mean. Frequency of the data lies mostly in the middle of the curve.

The distribution of the height of humans is a normal distribution. There are some tall very people and some very short people but most people are in the middle. What is most likely true about this tr?

In a normal distribution of human height, most individuals cluster around the average height, forming a bell-shaped curve. The extremes of very tall and very short individuals occur less frequently, resulting in fewer occurrences in these categories. This distribution indicates that while height varies, the majority of the population falls within a certain range close to the mean, reinforcing the idea of a typical "average" height.


The distribution of the height of humans is a normal distribution. There are some very tall people and some very short people but most people are in the middle. What is most likely true about this tra?

The distribution of human height being a normal distribution suggests that most individuals will cluster around the average height, forming a bell-shaped curve. This means that while there are extreme values on both ends (very tall and very short individuals), the majority of the population will fall within one standard deviation of the mean. Consequently, the likelihood of encountering someone whose height is close to the average is much higher than finding someone at the extremes.

How do you find the area of a triangle with two numbers and a dotted line in the middle?

To find the area of a triangle when you have two numbers representing the base and height, you can use the formula: Area = 1/2 × base × height. The dotted line in the middle likely indicates the height of the triangle, which is the perpendicular distance from the base to the opposite vertex. Simply multiply the base and height together, divide by two, and you'll have the area of the triangle.
