advantages and disadvantages of mean, median and mode psychology
EXAMPLE:For example,the median is only concerned with the middle number in a set of raw data, it doesnt consider any of the other scores. When you carry out a psychological experiment, you end up with a great deal of RAW DATA, usually in the form of 2 sets of scores one for each condition. It actually represents the average of the given collection of data. font-family: 'Questrial'; ELABOATION:This is a weakness because, only considering the middle score means that all other scores in the data set are ignored, from this, the accuracy of the median can be questioned how can this be an accurate measure of central tendency if it doesnt take all the scores in the data set into consideration? Many of these will be more than the inter-quartile range (IQR) away from the median (or mean) and they cannot all be outliers. DISADVANTAGES. Before anything else you must ask What measure of centrality is best for this problem? You cant divorce the answer from the original question. But it is easily affected by any extreme value/outlier. For example,in order to calculate the mean of the data below. Advantages. Mean Median Mode | MathDada 1. . Evaluation (AO3) of the Median as a Measure of Central Tendency. Mean: The mean takes account of all values to calculate the average. For example, if a data set includes numbers ranging from 2 to 100, the Mean of these numbers would be 51. Mean is typically the best measure of central tendency because it takes all values into account. They each try to summarize a dataset with a single number to represent a "typical" data point from the dataset. It is also useful when dealing with ordinal and discrete data, such as test scores in which the values are not continuous. Some key advantages include: Greater statistical power and more ability to extrapolate to the greater population Evidence-based More likely to observe an effect, due to combining smaller studies into one larger study Increased accuracy, because smaller studies are pooled and analyzed color: #3a3534; Measures of central tendency: Median and mode - ResearchGate It is suitable for further algebraic treatment. Gaps between the values aren't equal so a mean cannot be used to assess central tendency. Advantages: Averages are easy to calculate, most people do not need an explanation of what average is.

In such cases, it may be better to consider using the median or mean, or group the data into appropriate intervals, and find the modal class. Central is more applicable to the mean and median. Here we will get to know about the advantages and disadvantages of mean median mode. Mode is readily comprehensible and easy to calculate. MODE The mode has an advantage over the median and the mean as it can be In addition, the mode does not tell you anything about the data distribution or the percentile ranges of the data set.
