Quantitative data can't be displayed in

bars in a histogram are drawn adjacent to each other with ........ between them.

most-used measure of central tendency

better measure when a data set includes outliers.

mean > mode (مهم)

mean < Mode

A shot-put player records the following scores, 16.8 m, 16.9 m, 17.1 m, 17.2 m, 17.8 m, 17.9 m, 18.2 m, 18.3 m, 18.3 m, 18.5 m. Find the 1000 trimmed mean.

what is mode of that 1,1,2,3,4,5,8,7,5,8,6,9,8,2,8

A shot-put player records the following scores, 16.8 m, 16.9 m, 17.1 m, 17.2 m, 17.8 m, 17.9 m, 18.2 m, 18.3 m, 18.3 m, 18.5 m. Find the 10% trimmed mean.

When constructing a comparative bar graph we use the ............. rather than the ............

The mean, median, or mode by itself is usually a sufficient measure to reveal the shape of the distribution of a data set.

is the simplest measure of dispersion to calculate

Range

What is the Range of these value 25,8,4,5,75,96,51

range is very satisfactory measure of dispersion

The greater the amount of variability in the sample, the larger the magnitudes (ignoring the signs) of the deviations.

is the most-used measure of dispersion.

In general, a Large value of the standard deviation for a data set indicates that the values of that data set are spread over a relatively smaller range around the mean.

A particular deviation is positive if the corresponding x value is greater than x bar and negative if the x value is less than x bar

The standard deviation of the widths (in cm) of a group of 25 leaves is 0.9 cm. What is the variance of their widths?
