When was there more variation? (PLEASE ANSWER ASAP AND CORRECTLY, I WILL AWARD BRAINLIEST) (image below)

These bar graphs do not show the amount of variation in the population.

There was the same amount of variation in spot size 40 years ago and last year.

There was more variation 40 years ago.

There was more variation last year.

Answer:

There was more variation 40 years ago. Because 40 yrs ago the spot size was more to the right last year the spot size was more in the middle.

Explanation:

Answer:

there was more variation last year

Explanation:

so here's my thinking- 40 years ago the guppies' spot size ranged from 5-10 and last year they ranged from 3-9 seeing as how 10-5 is 5 and 9-3 is 6 and how 6>5 there was more variation last year compared to 40 years ago.

good luck :)

i hope this helps
