Frequency Distribution Table

Slide 2:

In this presentation the classes will be given. Goals : 1) To find frequency, cumulative frequency . 2) To create a frequency table. 3) To find the Mode

Slide 3:

Organize the data below in a frequency distribution table and find the mode. Miles driven from and to work 1 6 8 2 3 7 4 1 7 1 4 8 2 3 4 7 6 8 1 4 2 4 3 8 1 4 2 1 6 8 8 1 8 1 2 7 2 2 3 6

Slide 4:

1 6 8 2 3 7 4 1 7 1 4 8 2 3 4 7 6 8 1 4 2 4 3 8 1 4 2 1 6 8 8 1 8 1 2 7 2 2 3 6 Just looking at the raw data, it is difficult answer some basic questions like . . . We will do some summary STATISTICS on this data set to help us to understand this data set.

Slide 5:

Distance ( Miles ) Tally Frequency 1 2 3 4 5 6 7 8 Frequency Distribution

Slide 6:

1 6 8 2 3 7 4 1 7 1 4 8 2 3 4 7 6 8 1 4 2 4 3 8 1 4 2 1 6 8 8 1 8 1 2 7 2 2 3 6 Distance ( Miles ) Tally Frequency 1 2 3 4 5 6 7 8

Slide 7:

First we will tally the data.

Slide 8:

1 6 8 2 3 7 4 1 7 1 4 8 2 3 4 7 6 8 1 4 2 4 3 8 1 4 2 1 6 8 8 1 8 1 2 7 2 2 3 6 Distance ( Miles ) Tally Frequency 1 2 3 4 5 6 7 8

Slide 9:

1 6 8 2 3 7 4 1 7 1 4 8 2 3 4 7 6 8 1 4 2 4 3 8 1 4 2 1 6 8 8 1 8 1 2 7 2 2 3 6 Distance ( Miles ) Tally Frequency 1 2 3 4 5 6 7 8

Slide 10:

1 6 8 2 3 7 4 1 7 1 4 8 2 3 4 7 6 8 1 4 2 4 3 8 1 4 2 1 6 8 8 1 8 1 2 7 2 2 3 6 Distance ( Miles ) Tally Frequency 1 2 3 4 5 6 7 8

Slide 11:

1 6 8 2 3 7 4 1 7 1 4 8 2 3 4 7 6 8 1 4 2 4 3 8 1 4 2 1 6 8 8 1 8 1 2 7 2 2 3 6 Distance ( Miles ) Tally Frequency 1 2 3 4 5 6 7 8

Slide 12:

1 6 8 2 3 7 4 1 7 1 4 8 2 3 4 7 6 8 1 4 2 4 3 8 1 4 2 1 6 8 8 1 8 1 2 7 2 2 3 6 Distance ( Miles ) Tally Frequency 1 2 3 4 5 6 7 8

Slide 13:

1 6 8 2 3 7 4 1 7 1 4 8 2 3 4 7 6 8 1 4 2 4 3 8 1 4 2 1 6 8 8 1 8 1 2 7 2 2 3 6 Distance ( Miles ) Tally Frequency 1 2 3 4 5 6 7 8

Slide 14:

1 6 8 2 3 7 4 1 7 1 4 8 2 3 4 7 6 8 1 4 2 4 3 8 1 4 2 1 6 8 8 1 8 1 2 7 2 2 3 6 Distance ( Miles ) Tally Frequency 1 2 3 4 5 6 7 8

Slide 15:

1 6 8 2 3 7 4 1 7 1 4 8 2 3 4 7 6 8 1 4 2 4 3 8 1 4 2 1 6 8 8 1 8 1 2 7 2 2 3 6 Distance ( Miles ) Tally Frequency 1 2 3 4 5 6 7 8

Slide 16:

1 6 8 2 3 7 4 1 7 1 4 8 2 3 4 7 6 8 1 4 2 4 3 8 1 4 2 1 6 8 8 1 8 1 2 7 2 2 3 6 Distance ( Miles ) Tally Frequency 1 2 3 4 5 6 7 8

Slide 17:

Next we will find the frequency for each distance. The frequency shows how many are in each distance.

Slide 18:

distance ( Miles ) Tally Frequency 1 2 3 4 6 7 8 8 7 4 6 4 4 7 The frequency tells “How many?” It changes the Tally into a Number . How many 2 miles? How many 1 mile? How many 3 miles? How many 4 miles? How many 6 miles? How many 7 miles? How many 8 miles? ? ? ? ? ? ? ?

Slide 19:

Organize the data below in a frequency distribution table and find the mode. Number of calls per day made by employees Practice: 1 4 9 5 2 3 3 2 4 5 6 1 8 5 5 3 8 3 4 3 4 6 8 6 1 8 7 6 2 2 4 9 6 3 2 9 7 2 8 7
