 Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What term refers to the pattern describeing the distrubtion of many physical and psychological attributes where most scores fall near the average and fewer scores lie near the extremes?
 A Standardization B Normal Curve C Reliability D Validity
Explanation:

Detailed explanation-1: -Most of the continuous data values in a normal distribution tend to cluster around the mean, and the further a value is from the mean, the less likely it is to occur.

Detailed explanation-2: -Normal Curve: The symmetrical bell-shaped curve that describes the distribution of many physical and psychological attributes. Most scores fall near the average, and fewer and fewer scores lie near the extremes.

Detailed explanation-3: -Graphs, pie charts, and curves are all ways to visualize data that psychologists collect. When data is visually represented, it is known as a distribution. If it’s simply the representation of a few data points we’ve collected, it’s a frequency distribution.

Detailed explanation-4: -In Psychology, this information can help researchers make assumptions about the way in which populations are distributed. Normal Distribution Curves. = arrangement of data that is symmetrical and forms a bell-shaped pattern. The mean, median and/or mode all are shown in the centre at the highest peak.

Detailed explanation-5: -Normal distributions have key characteristics that are easy to spot in graphs: The mean, median and mode are exactly the same. The distribution is symmetric about the mean-half the values fall below the mean and half above the mean. The distribution can be described by two values: the mean and the standard deviation.
