Mean = Sum of data values/Total number of data values = (40 + 50 + 55 + 78 + 58)/5 = 281/5 = 56.2 . Therefore, the mean for the given data is 56.2. 2. A class consists of 50 students, out of which 30 are girls. The mean of marks scored by girls in a test is 73 (out of 100), and that of boys is 71. Determine the mean score of the whole class ...

Mean Median Mode Range Worksheets. The mean median mode range is the entry-level topic under the bigger umbrella of statistics. Mean refers to the average value of the population of data. Median refers to the central value of the data but before finding it, all the values must be arranged in a decreasing or increasing order.
Definition. The median is usually described as the ‘middle number’. We can obtain the median by ordering the data in terms of size, then: For an odd number of observations, simply take the middle number. For an even number of observations, take the two middle numbers, add them together and divide by $2$. When you have a large data set it is ...
5 − 7 = −2 11 − 7 = +4 6 − 7 = –1 11 − 7 = +4 14 − 7 = +7 20 − 7 = +13 ∑ = −7 ∑ = +29 the mode is the least stable of the three measures of central tendency. this means that it will probably vary most from one sample to the next. assume, for example, that we send these same 11 children on another equally difficult
