In the second calculation, the frequencies are 3, 2, 1, and 5. What would be the best measure of the center? Statistical software will easily calculate the mean, the median, and the mode. A frequency table is a data representation in which grouped data is displayed along with the corresponding frequencies. A data table shows the number and percent of employees in each of the four categories: daytime employee, daytime manager, nighttime employee, and nighttime manager. From this chart you can see that our data set is 6, 7, 8, 8, 6, 0 and 7.

The trend line Y = 0.05 + 0.005 t was calculated from quarterly data for 2000 - 2004, where t = 1 for the first quarter of 2000. (See Sampling and Data for a review of relative frequency). Performance & security by Cloudflare. Line graph. Examples of these measures include the mean, median, and mode. Spread Statistics Measures & Examples | What are Spread Statistics? The trend value for the second quarter of the year 2005 is 0.75. The mode is $25,000 and occurs 150 times out of 301. A statistic is a number calculated from a sample. To calculate the mean from a grouped frequency table we can apply the basic definition of mean: \[mean = \dfrac{\text{data sum}}{\text{number of data values}}.\].
