A set of eight systolic blood pressures is given.
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | |
| Pressure | 110 | 123 | 135 | 155 | 129 | 116 | 101 | 122 |
(a) Find the median value for the dataset.
(b) Find the values of the lower and upper quartiles.
Note: you should do this by hand using the method discussed in
class. Some software packages and calculators use a slightly
different technique and will report different values.
Q1 =
Q3 =
(c) Find the value of the interquartile range (IQR).

I was given a sample data set of systolic blood pressures and
was asked to 1.) calculate: the mean, median, standard deviation,
interquartile range and 2.) applied what I have learned in the
course to describe or comment on the systolic blood pressures
data.

Test the significance of the correlation coefficient.
Then use math test scores (X) to predict physics test scores
(Y). Do the following:
Create a scatterplot of X and Y.
Write the regression equation and interpret the regression
coefficients (i.e., intercept and slope).
Predict the physics score for each....

This is my dataset
Find mean, median, mode, variance, standard deviation,
coefficient of variation, range, 70th percentile,
3rdquartile of the data and skewness and define what
each of these statistics measure. For example, mean is a measure of
the central tendency, what about the rest?
