$1.$ Construct a tally sheet of something that is of interest to you. If you have a job, look at types of defects produced over a period of time $($this is easy if you can find a scrap bin and can identify the types of defects$).$ Or$,$ you can simply visit a restaurant and record the types of mistakes you see being made around you by the waiter, greeter, cook, bus boy, etc.. It doesn$$t need to be mistakes. Have an interest in the types of trees in your yard or a nearby park $$ take a walk around and construct a tally sheet of them. Want to know the makes of cars in the parking lot...I think you get it$.$

$2.$ Construct a Pareto chart of something that is of interest to you. This may be done quickly and easily by organizing the data in the tally sheet exercise in descending order. Or$,$ pick something else...

Describe how you might use weighting or successive Pareto analysis to the data that you have collected.

$3.$ Construct a Cause and Effect diagram for some event. You may want to use the top item from the Pareto analysis exercise...or not. It can be negative $($bad food, slow service, defects, etc.$)$ or positive $($good products$/$service$,$ good grades, submitting assignments$/$getting to work on time, good health, good food, etc.$).$

$4.$ Construct a check sheet for a process that you are familiar with. It can be as simple as getting to work$/$school$,$ or it may be a process that you use at work$/$school; or something that is more fun like planning a vacation.

$5.$ Construct a process flow diagram for a process that you are familiar with. It may be possible to put the events in the check sheet in sequence. Include at least one decision.

$6.$ Construct a run chart of some data that is in time order sequence. This one may be a little tricky, because the time interval should be the same $($hourly$,$ daily, etc.$)$ and it has to be some sort of measurement. For example, daily $($or hourly$)$ temperatures or precipitation $($amount or $\%$ chance$)$ for a given location. Use at least $25$ data points.

$7.$ Construct a histogram of the data from the run chart. This one could get complicated, but try to keep it simple. Use about $6$ or $7$ bars. For example, if you have a run chart of daily temperatures and they range from $40$ to $80,$ divide the difference $(40)$ by $6.$ This gives you a range of between $6$ and $7$ degrees per bar. I$$ll pick $7$ degrees $($odd numbers gives you a clean midpoint for the bar$).$ So$,$ the first bar would be the days between $40$ and $46,($six numbers: $40,41,42,43,44,45,46),$ with a midpoint of $43$; the next bar would be the days between $46$ and $52,$ etc.. Don$$t worry about perfection. It is ok to make mistakes on this. Just try it and do your best.

$8.$ Construct two scatter diagrams, one for factors that have a high positive correlation and one for factors that have a high negative correlation.$$ It is ok to "make up$"$ the data.$$ think you get it$.$
