<u>Explanatory variable</u> (independent variable)
- The variable that affects the other variable.
- Drawn along the horizontal axis.
<u>Response variable</u> (dependent variable)
- The variable that is being affected.
- Drawn up the vertical axis.
(a) As the class wondered if they could <em>predict the father's height</em>, when they<em> know the son's height</em>
Explanatory variable = son's height
Response variable = father's height
(even though this is contrary to real-life, where the father's height would be used to predict the son's height)
(b) **see first attachment**
(c) The association is positive since the father's height increases as the son's height increases.
(d) **see second attachment**
Outlier = Paul (64.5, 73)
This point is far away from the majority of points on the scatter plot.
If we add a regression line to the scatter plot, we can see that this data point is the farthest from the regression line.
Answer:
mean=14
median =4
Range=3
Step-by-step explanation:
Mean = 4+6+3+1+9+0+5/2
=28/2
=14
Median = ( N+1/2 )th item
= ( 7+1 )/2
= 8/2
= 4
Range = largest no- lowest no
= 9-6
= 3
Answer:
-42.86%
Step-by-step explanation:
Mathematically, the percentage change is;
(new value -old value)/old value * 100%
According to this question
new value = 63
old value = 90
Inputing these values we have ;
(63-90)/63 * 100
-27/63 * 100%
= -3/7 * 100% = -42.86 #
