No. of cars sold 2500 3200 4000 5100 6200 7500
[a] What scale was chosen?
[b] What is the median of the data?​

Answer 1

Answer:

Median = 3.5

Step-by-step explanation:

Step 1: Any group's median is the value that falls in the centre. At this stage, half of the data are greater and half are less. The median makes it possible to express a lot of data points with only one. The median is the most straightforward statistical metric to compute. The middle data point reflects the median of the data after the data are organised in ascending order for the purpose of calculating the median.

Step 2: One of the three measurements of central tendency is the median. The centre position of the data set is noted while discussing a set of data. This is referred to as the central tendency measure. The mean, median, and mode are the three most often used metrics of central tendency.

Step 3: [a]  3200 -2500=700

4000-3200=800

5100-`4000= 1100

6200-5100= 1100

7500-6200= 1300

[b]   The median of the data is

[2500, 3200, 4000, 5100 ,6200, 7500]

Median = [(n + 1)/2]th term

= (6 + 1)/2th term = 7/2th term = 3.5

Median = 3.5
