a population for which a mean/median/mode would be appropriate? Inappropriate? The analysis of data begins with descriptive statistics such as the mean‚ median‚ mode‚ range‚ standard deviation‚ variance‚ standard error of the mean‚ and confidence intervals. These statistics are used to summarize data and provide information about the sample from which the data were drawn and the accuracy with which the sample represents the population of interest. The mean‚ median‚ and mode are measurements of the

distribution - most values are concentrated on left of the mean‚ with extreme values to the right. Skewness < 0 - Left skewed distribution - most values are concentrated on the right of the mean‚ with extreme values to the left. Skewness = 0 - mean = median‚ the distribution is symmetrical around the mean. Kurtosis - indicator used in distribution analysis as a sign of flattening or "peakedness" of a distribution. Interpretation: Kurtosis > 3 - Leptokurtic distribution‚ sharper than a normal

average) is most likely the measure of central tendency that you are most familiar with‚ but there are others‚ such as the median and the mode. The mean‚ median and mode are all valid measures of central tendency‚ but under different conditions‚ some measures of central tendency become more appropriate to use than others. In the following sections‚ we will look at the mean‚ mode and median‚ and learn how to calculate them and under what conditions they are most appropriate to be used. Mean (Arithmetic)

The data for credit balance shows that it has a normal distribution with no skew. The Mean (3970)‚ Median (4090)‚ and Mode (3890) are all within very close proximity and the Mean is at the peak of the chart. All other data points fall nearly equal on either side of the Mean. The standard deviation is fairly high at 931.9. In the next graph we will
